[tbnl-devel] Problem with file uploads

[Tiarnán Ó Corráin]

Hi--

I'm using tbnl to run a site (educational in purpose), which will be
rich in texts and images. I want people with the appropriate
privileges to be able to upload images to the server, where various
incantations will be performed to ensure that the images are formatted
correctly for the site.

However, I seem to be running into a problem with either mod lisp or
tbnl, for images >=~1MB. When I try to upload an image of this site,
an internal server error is returned after a few seconds, and the
converted image (using imagemagick) appears in the thumbnail gallery
with a portion of the bottom shown in grey, as if the image did not
upload completely to the server.

Is there some configurable upper limit to the size of file uploads, or
can someone point me to the likely source of the problem?

regards
