corrupt images

how to find them

[omoutop]

Hi all...

Is there a way to find if an image file is corrupt? I mean i can scan a folder and create an image listing, but can I , using php, find if an image is corrupt without echo/print the image source file on screen?

Thanks

I doubt its possible to detect a corrupt image omoutop. If you know the correct file size of the image, you can compare that to see if its correct. The file_exists() function will only detect whether the image exists or not, so as far as I know, only comparing the file size gives you a slight clue as to whether the image is ok or not.

I thought it might be impossible. I google for this for more than 1 hour and i found nothing. Thought i give it a try here.

Of course it's impossible for me to know the original file size of the images (unless i save it to db during upload process - which is tooooo late now).

Anyway, thanks for confirmation on an impossible task :)
