php generating not valid images

[Drekey]

I've a little code that uses the SimpleImage class with which I create scaled images.

Right after that is done, I launch a code using CropCanvas class to crop the scaled image.

Unfortunatly the CropCanvas can't work on the SimpleImage resulting image cause it says the is not a valid PNG/JPG/etc.


Any ideas?

That was... vague. You're asking doctors to diagnose your condition with nothing but a note about some apples you ate the other day.

Provide some code. In all likeliness, you are saving the files wrong(or not saving them at all) before attempting to use them.
