When I was trying to get_hard_copy, it complains that

Can't open log file: path= /usr/local/webwork/system/courses/demo/html/tmp/Temp_downloadAllSets_professor.log No such file or directory

Here is the directory permission [tmp]$ ls -al total 32

What's the permissions of /usr/local/webwork/system/courses/demo/html/tmp/ and what user/group is your webserver running under?

EDIT: Somehow I missed the first line of that ls output....nothing to see here....

As you can tell from the first post, it is world-readable-writable.

Did you set $imageDebugMode = 1; as discussed in http://webhost.math.rochester.edu/webworkdocs/discuss/msgReader$2326

Most likely there is some problem with tex or pdf output.

These are regular tex errors. (Nothing to do with either dvipng or WeBWorK, as far as I can tell.) You will need to get the tex and latex programs operating properly first. You can test these on any tex file (e.g. a math paper) using

latex mathPaper.tex

Your local unix people can probably help you get tex and latex running on your unix machine. This page may help some http://www.tug.org/interest.html

I'm not a real expert on this but the first question that arises is: Do you have TeX installed (e.g. the teTeX distribution)? What do the commands locate latex.fmt and locate tex.pro return?

In the tmp directories you will see (since I assume you have set $imageDebugMode = 1) raw tex files (with a .tex extension). You should run them (or some other test file) through tex to make sure tex is working on your system. By the way, what operating system are you running under?
