I have run into problems as well with JPGs exceeding 1MB in size. Symptoms include upload confirmation pages that are blank, blank pages displayed when previewing/saving Wiki pages with thumbnails of the images, or 'Fatal Out of Memory' errors. I have no problems displaying the full-sized image.
My MediaWiki installation is on a shared hosting server, which has limits on the amount of available memory I can use. My suspicion is that the GD code used to create the thumbnails is exceeding available memory - before it can create the thumbnail, it first uncompresses the JPG. I have been trying to install ImageMagick on the sharing hosting server, but have not figured out all the changes required to the Make files so that it will install cleanly. Installing just the ImageMagick binaries was not successful. There are other, JPG-specific thumbnail conversion routines provided with Linux that appear to be less memory-hungry, but I suspect that would require changes to the MediaWiki code. Norbert

This will work, but you might want to find out what's causing the errors
in
the first place and tackle the original problem. What are the warnings
and
errors you're getting? What image renderer are you using?
I also encountered this problem. However it does not seem to be related with the bytesize but more with the imagesize. Whenever an image exceeds the size of approximately 1600 x 1600 pixels, the "Fatal Out of Memory" errors occur. It is, as Norbert says, only when Thumbnails are involved...
Kind Regards,
