Thanks, I think I have a much better idea what's going on. However I'm still getting the "failure to parse" error. At first I had set owner to _www and I couldn't, with my user, get texvc to make the png. I made a new tmp with me as the owner and then I was able to produce the png. I chmoded tmp to 777. What permissions/who needs to own tmp in order for it to work? If it worked, would there be a png left in the tmp folder? Thanks again.
