500 errors based on uploads

[richrock]

Well, I managed to sort out the image uploads for my local server, and I can resize images based on some pre-defined criteria...  Not a problem there - it's got a good process, and I'm usually resizing with about 80-90% quality, creating images around 7-300k.

 

I've uploaded this to my online test server, and I cannot upload more than 2mb of images without getting a 500 Internal Server Error.  Spent all morning trying to figure out why - here's what I've done:

Tried ini_set() on the actual script.  Nothing.

Created a php.ini based on some tutorials - registers the changes using phpinfo, but again, cannot upload two images, or larger than 2mb.

Copied an existing php.ini from a site I did where it is working allowing video uploads of 32mb.  Doesn't work.

Used unset() on most variables in the image processing script - this got me as far as managing to make images upload, again up to 2mb.

 

Here's the php, which all it has to do is process a maximum of 3 images, resizing them into 3 sizes, and then copying the original into a hires backup folder.  Not too hard huh?

How about using ajax to submit files one at a time? (or onclick loop through, submitting them one at a time)

[richrock]

Sorry, wouldn't have a clue how to do these - onclick loopthrough sounds good tho.  Where could I get more info about this?
