Re: 1,2MB image upload error
What is the width and height of that image in pixels?
Suppose the image is 2048×1526, 24-bits. That’s 2048×1526×3 = 9437184 bytes (even if it’s much smaller as a JPEG file)
With bigger images and perhaps some auto-thumbnailing going on, combine that with the memory usage of TXP itself and you may very well exceed the memory limit.

Re: 1,2MB image upload error
At an absolute minimum, that image requires about 16mb of memory, not counting overheads. If PHP’s image processing files make a copy of the image in memory (something we have no control over), you can at least double that. Your memory limit setting is at 24mb. Textpattern itself typically uses 2-4mb.
I checked in a tentative change that attempts to increase the memory limit to 32mb when resizing images (svn r2263). It needs testing.

How much EXTRA_MEMORY is MORE_MEMORY?

Re: 1,2MB image upload error
Looks like a hard-coded limit. Does this mean that MORE_MEMORY is less memory if the limit was set higher in php.ini?
Even if such an approach works, should scripts bypass a memory limit set by the webhost?
Another way to solve this may be to predict how much memory is needed based on the image size and skip thumbnailing if it gets too close to the memory limit. In those cases the user can either upload thumbs manually or have the limit increased by the webhost. Because, no matter how high you set MORE_MEMORY, people will upload even bigger images and still run into the memory limitations.

Hmm, for me it looks like a typo, but as I’m more experienced in stronger typed languages this might be another PHP specifity I just don’t know of yet.

Heh, I hadn’t even noticed that it said ‘extra’ in the define :)

Re: 1,2MB image upload error
I would say yes, it’s a typo.
