I want to organise my files inside the backend as lossless .png files, but I want the CMS to deliver them as compressed .jpg files. That way I must not keep the .png files somewhere else, just to make sure I have the best quality images ready to use again.
What's the best way to setup this?
Does it make sense to add an extension to the Image object using the GD lib? And is it possible to find out if a .png file uses alpha and - because of that - has to be delivered as .png and not as .jpg?
Thanks for any help.
