Unable to open Image in C++ SDL - c++

Question

So im trying to render an image. This code worked fine before I refactored into seperate classes but i cannot see the problem. The file path for the image also worked before the refactoring however i have not moved the image so it should still be in the same place.
The error i am getting is "Unable to create texture from surface. Error: Couldn't open Images/text.bmp" so im fairly certain its the line of code below that is messing up.
if (!(gTexture->LoadFromFile("Images/text.bmp")))
{
return false;
}
Here is the LoadFromFile function code
bool Texture2D::LoadFromFile(string path)
{
Free();
SDL_Texture* pTexture = NULL;
SDL_Surface* pSurface = IMG_Load(path.c_str());
if (pSurface != NULL)
{
//SDL_SetColorKey(pSurface, SDL_TRUE, SDL_MapRGB(pSurface->format, 0, 0xFF, 0xFF));
pTexture = SDL_CreateTextureFromSurface(mRenderer, pSurface);
if (pTexture == NULL)
{
cout << "Unable to create texture from surface. Error: " << SDL_GetError() << endl;
}
mWidth = pSurface->w;
mHeight = pSurface->h;
SDL_FreeSurface(pSurface);
}
else
{
cout << "Unable to create texture from surface. Error: " << IMG_GetError() << endl;
}
mTexture = pTexture;
return pTexture != NULL;
}
Below is the Source.cpp file:

while(!quit)
{
//gTexture->Render(Vector2D(), SDL_FLIP_NONE, 0);
Render();
quit = Update();
}
}
CloseSDL();
return 0;
}
bool InitSDL()
{
if(SDL_Init(SDL_INIT_VIDEO) < 0)
{
cout << "SDL did not initialise. Error: " << SDL_GetError();
return false;
}
else
{
//ITS ALL GOOD BRO
gWindow = SDL_CreateWindow("Games Engine Creation",

return false;
}

if (gRenderer != NULL)

return false;
}
void Render()
{
SDL_SetRenderDrawColor(gRenderer, 0xFF, 0xFF, 0xFF, 0xFF);
SDL_RenderClear(gRenderer);
gTexture->Render(Vector2D(), SDL_FLIP_NONE, 0);
//SDL_Rect renderLocation = { 0, 0, mWidth, mHeight };
//SDL_RenderCopyEx(mRenderer, mTexture, NULL, &renderLocation, 0, NULL, SDL_FLIP_NONE);
SDL_RenderPresent(gRenderer);
}

A simple way to start debugging is to place the image in the same folder with the executable and show the path as ./image.bmp to see if something is wrong with the path.
