General Support: random-images and latest-images files stay blank with new plugin

I have successfully upgraded our plogger installation, but the random and latest images I had on our website didn't show anymore. That is, the spaces and links are there, but the thumbs themselves not anymore as they have a different url now. So I thought I'd try the new plugins, but then nothing comes up. I looked at the pages in the plugin directories themselves, but unfortunately they are blank :(

I have searched for hours, but can't figure out why it's not working. Does anyone have an idea?

If someone would know how to add the album name to the thumbs to be taken out of the database in the OLD codes, I'd be happy too (at least that seemed to be the only issue)!

thanks!
