I am trying to delete old images from my ECR repositories. I was going to do it by deleting images, that have not been pulled longer than X days.
This API gives https://docs.aws.amazon.com/AmazonECR/latest/APIReference/API_ImageDetail.html the lastRecordedPullTime. However this property is missing on majority of images (I have hundreds of thousands of images some of them older than 5 years).
I guess this property is missing if image was never pulled, but number of these images is marginal.
My theory would be, that this property is deleted after the some amount of time, during which image was not pulled. If so what is the amount?
Or is there another reason why is lastRecordedPullTime property missing?

My application stores MANY MANY images in S3 - we use Rails 5.2 ActiveStorage for that. The images are used a lot for 6 to 9 months. Then they are used VERY rarely until they are 15 months old and deleted automatically by ActiveStorage.
To save some money I'd like to move the files from 'S3-Standard' to 'S3-Infrequent Access (S3-IA)' after 9months of the file creation (This can be done automatically in AWS).
My question is: Will ActiveStorage still be able to find/display the image in 'S3-IA' in the rare case someone wants to see it? Will ActiveStorage still be able to find the file to delete it at 15months. Bottom Line: I don't want ActiveStorage to loose track of the file when it goes from 'S3-Standard' to 'S3-IA'
S3-IA just changes the pricing of an object. It doesn't change the visibility of the object, or the time needed to retrieve it (unlike GLACIER storage class).
One thing to be aware of is that IA pricing is based on a minimum object size of 128k. If you have a lot of objects that are smaller, then your costs may actually increase if you save them as IA.

I haven’t tested, but Active Storage should be able to find the object as long as its name doesn’t change.
I am building an ionic 3 app and I want to set up an upload based on the ImagePicker Cordova plugin.
I use Dexie to persist some data, and I wonder if persisting whole base64 strings would be alright. Or is it too heavy?
I want to persist the images chosen with the image picker. When an upload is suspended or stopped i would be able to restart the upload for those.
Anybody using any other type of persistence of Base64 images?
Thank you
It depends on the size of the images. Unless images are larger than 10 megabytes, I think you are safe. There is no direct limit of document sizes in indexedDB except for the quota you are given for the whole db instance, which can vary per platform and can be extended on modern platforms using navigator.storage.persist(). Do not index the property containing the large string though, since it would affect performance badly and eventually trigger unknown bugs.
In case you target modern platforms (Chromium, Firefox and Safari 10.1), you don't need to convert the images to base64. Instead you can store the binary data directly in a property of type Uint8Array.
I am looking for a way to make small, medium, and large copies of an image automatically when uploaded through CKFinder 2.5. Basically I want the same image copied and resized to different sizes so that I can use different images for my responsive site. The imageresize plugin does similar, but not quite what I am looking for since it is still initiated by the user.
I would prefer to add the code to the config file over adjusting code in the core folder. I am using coldfusion, but I would appreciate ideas in any language possible so I can make something work. Thanks in advance!
How can we handle out of memory error?
One of our customers contacted us and said when he uploads images, face with this error
out of memory
I asked about size of images he said 4MB, but I could upload even a 7 MB image successfully.
So I tried to upload big images until I faced the error, most of them uploaded successfully but I faced the same error when uploading some of them
I found that error was not related in size of image, it's related to width and height of image
You can understand better by look at this link
memory error
but I don't know what exactly max-width and max-height are, that I can validate to prevent this error.
I forgot to say, also I resize images dynamically.
But I can't say to users resize your images because them take large pictures with their phone but maybe some of them didn't know how can resize images with photoshop.
please help
Ideally you should restructure your code to use less memory.
There are ways to decrease the memory overflow for any JVM process.
just give the JVM more memory with the -Xmx option.
You should decode with inSampleSize option to reduce memory consumption.
Another option inJustDecodeBounds can help you to find correct inSampleSize value

I have started a news website for a specific area of business one year ago. The website lists news and for every post there is a featured image. Unfortunately, there have been posted about 1500 news in a year and the website is taking 1,07Gbytes of space. This seemed totally insane to me as joomla is had been only some Mbytes and there were no big additions from my side (like files or graphics etc.).
I did a HUGE mistake. I trusted the joomlaworks guys and installed K2. The main reason I did this was that the default joomla article manager did not offer to save a featured image for each post. But this was added in the new 3.0 version !
K2 does something extremely foolish. If you save a photo of 2 Mbytes, then it will save the original and 4 additional ones, one for each size (Small, Large, Medium, XL). Insanely, you upload a 2Mb image and it ends occupying 4Mbytes of space !
The hosting provider gives me 2Gbytes of space to store my files. I have started to lose my sleep at night because the space expands day by day and If gone beyond 2Gbytes, I will have to upgrade the hosting plan and I do not have the money to do this.
I believe I have three choices:
Move all items, categories, images from K2 back to Joomla articles that is much faster and then upgrade to version 3.0 which supports featured images. This seems extremely difficult and I do not know If it's possible at all. Even If I move all table rows from K2 to Joomla, I don't feel comfortable with 1500 ones and the images' paths are not saved in the db. Chaos.
Move everything to wordpress. No idea how to do that at all.
Compress the images that are in cache or search for ways to stop K2 doing that.
k2 saves the images in two different folders. One folder holds exclusively the originals, and the other folder holds all the resized versions. Technically you can just delete the folder with the originals because those are not the ones used in the articles or anywhere else on the website. Let's not speak poorly of k2 because they save the originals. I think it's a good feature. I once needed to go into that folder on my host and find a file that was deleted from my computer. Also you could easily in the future use that folder to rebuild all the resized files in case you want to change the sizing in layout.
I would just back up the folder every once in a while and delete the copy on your host. That should save a lot of space. Also you can set an option that the resized files are lowered in quality so they don't take up so much space. There is an option in the back-end. At 70-80% the photo quality is still great.
Why do you think that creating small, medium and big image is extremely bad? Do you actually have preview of the image, where it appears in a smaller size? If so - this is a wise way to do it.
If you really do not use any of smaller images - I would recommend go line by line through K2 plugin (or whatever it is) and find where exactly are the lines with saving these additional images and comment them.
Just another thing. How you ended up with 2 Mb images for a news site. In my opinion this should be really high resolution images, because the normal size is like 300kb.
In the folder www__TemplateName__\media\k2\items you will see two subffolders "cache" and "src" - the later one is for source files. Contents can be safely moved out to a local drive once a month. Yet, I'd say if you end up with 1.5k news, datadase would take lots of space too. And most hosters count database space in too. And you won't be able to do ANYTHING about it - you just can't throw away DB...
Then, most likely you have email server on the same host even though you don't use it (probably). If you have 1.5k news in one year - I can imagine how much spam would end up in your mail folder - that takes space out of your 2 gigs at hoster... Check your mail folder - kill all what you don't need there...
You're saying "I need an answer from a joomla expert here" - Joomla expert won't tell you much - k2 expert is needed. And the answer was given - reduce the quality of image cashed by k2 to 70% - it'll do just great - save lots of space and the quality drop won't be visible - this setting is set once and works for all authors...
In the case with DB, I'd highly recommend to have http://extensions.joomla.org/extensions/access-a-security/site-security/site-protection/14087 installed and then click Clean Temp and Repare Tables - it helps too.
Then, one other thing is to batch resize files in original's folder for k2 - there're tonns of different scripts for that in the pit of internet. Run it there from time to time and crazy big files from your users will shrink unbelievably!
But most of all - in these days, having a host of 2gigs??? That's crazy low. In my case $50 per year give me 6gigs - and that's not the cheapest host here... So... Change your host!
