[Mediawiki-l] Is there a way to limit the size of images uploaded

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 

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.
