Which version of CentOS? I use convert all of the time with CentOS 4.8,
using ImageMagick 6.0.7.1-20.el4 without any problems:
*Exactly* which version of CentOS, ImageMagick? i386 or x86_64?

I'd say that was true if the mystery server didn't serve images converted under Lenny just fine.
In fact, it was argued during the issue that it wasn't our fault, that it works under a standard web server just fine.
The fact remains, the Debian port of IM worked, the CentOS one didn't.* I've already worked around the issue,
I just do my conversions on Debian, being that I'm not really a Debian fanboy, I'm not terribly thrilled about maintaining
a Debian install around, and I figured I'd ask.
The provider is coresense.* For better or for worse.* They do a lot of things stupidly, but it works, and for lack of a
better option to suggest for a cart with a back-end that handles the things they do, it stays.

That suggests a problem with the way your "mystery software" is serving
the image rather than a problem with the image. *Which points to a bug
ImageMagick-6.2.8.0-4.el5_1.1 on CentOS 5.4 and never experienced any corruption here...
Did you try to convert an image several times and check that they are all the same?

Yep, I also looked into building:
[root@pythagoras SPECS]# rpmbuild ImageMagick.spec
error: Failed build dependencies:
*** perl-devel is needed by ImageMagick-6.5.8-6.x86_64
*** jasper-devel is needed by ImageMagick-6.5.8-6.x86_64
[root@pythagoras SPECS]#
But I couldn't satisfy those reqs.* I saw a post by Johnny about it, just didn't see the ultimate result.
