Using cfmail() (ACF2018), how does one go about adding in parameters? - coldfusion

Question

I have a function that sends e-mail which works fine in it's basic form. However I need to add in params for images and attachments and can't find any documentation other than the basic cfmail() functionality.
cfmail(
to = arguments.emailTo,
from = arguments.emailFrom,
subject = arguments.emailSubject,
type = 'html'
) {
writeOutput(arguments.mailbody);
}
I feel they should be up above the mailbody but can't find any docs on how to add them.

The linked documents above are great for new mail(), but - at least what I saw - were not updated for the newer cfmail() function. Here's the solution that also includes a boolean if one image is optional. I also found that in the included e-mail body, CID: does not show the image in Outlook (but is fine in Gmail), but cid: works in both.
private void function sendEmail (
required string mailbody,
required string emailTo,
string emailFrom = 'this is a subject line',
required string emailSubject,
boolean includeBoth = false
) output = false {
cfmail(
to = arguments.emailTo,
from = arguments.emailFrom,
subject = arguments.emailSubject,
type = 'html')
{
cfmailparam(file='C:\path\to\my\image\image.jpg', contentid='header', disposition='inline');
if (arguments.includeBoth) {
cfmailparam(file='C:\path\to\a\different\image\icon.png', contentid='icon', disposition='inline');
}
writeOutput(arguments.mailbody);
}
