Ok - I've finally got something that sometimes works. http://smada.com/images/hide_image.php

I dunno what you did to the first file upload button, but as soon as I choose the FIRST file, I get: Warning: imageistruecolor(): supplied argument is not a valid Image resource in /usr/local/psa/home/vhosts/smada.com/httpdocs/images/hide_image.php on line 60

That is strange. Doesn't happen to me. The javascript should just be making sure the images are a supported type.

I was using firefox. the javscript also calls the submit button of the form (if the file extension is okay - which is a nice check to do for honest people but won't stop B@d@@ssH@X3r from uploading a binary or whatever - so check the mime-type on the sideserver also) - maybe the call to the submit button doesn't work in IE.

Here is my best so far: http://smada.com/images/Snow.png (2 MB) (http://smada.com/images/Snow.jpg <-- not as big, but doesn't look as good either) These have to be opened in IE.

indeed, and may I be one to congratulate you - I love to see people keep hacking the problem/challenge and get it working. especially since what you are trying to do is quite manic (image manipulation is a heavy science, just ask the 200K/year guys at Adobe ;-). very cool indeed (pun intended!) :-)
