imagejpeg / imagecreatefromjpeg doesn't work with every image

[suffeks]

i'm upload images to a server, and watermarking them, for about 90% of the images this process works, but then i have some images where it doesn't, i get no errors, and the script just stops, there are no errors in my script, i'm just assuming the actual header in the jpeg file is different or formatted weird that the gd lib in php cannot understand it or something... so my question, how can i fix this or prevent these images from stopping my scripts...

i tried a true/false thing, but since it completely stops the script without output, that doesnt work...

help! lol

thanks

i figured it out, the image cannot be too big in dimensions, after a few hours testing all resolutions, the max is 2,495,000 square pixels.
