Hi

Thanx for the fast response to my problem

I have checked my memory limit in the php.ini file and it is 8mb as well =
on my offline server. i further noticed that on my online server it =
doesnt realy depend on the filesize in mb but rather the size in pixel. =
once i try to upload images larger than 1280*960 it gives me an error =
message. on my offline server this size is no problem.

I wonder why it tries to allocate so much memory in teh first place =
since the pics are not that big in size. the last one i tried was 300kb =
but had a resolution of 2272 / 1704px. its really weird.

Regards
J

Not really that strange. The internal manipulation format is
uncompressed so you can work out exactly how much memory it needs simply
by multiplying your resolution by the colour depth. The fact that it is
300k on your disk is completely irrelevant.

Are you sure that your local server was compiled with --enable-memory-limit?
The memory limit set in php.ini will only be enforced if you have
--enable-memory-limit.

That's because 2272 x 1704 x (3 bytes/pixel) = a lot of memory
