Well, I've searched around and found a lot of people poking
around at solutions, but I was unable to find one for me.
Here is the problem.
I can upload small pictures, but large pictures I get this error:
Fatal error: Allowed memory size of 10485760 bytes
exhausted at (null):0 (tried to allocate 8320 bytes) in
/home/virtual/site3/fst/var/www/html/resources/integral.php on line 1133
which is where I'm autothumbnailing the image.
When I upload something much larger I get a pop-up:
Document contains no data.
in Firefox and in IE I get:
Page cannot be displayed.
I have an upload class I'll show below. It was written by
somebody else but heavily edited by me. I know this
is a lot to ask, but upload handling is such a pain in
the butt. Please take a look and let me know what you
think might be causing the problem.
