Hey there,
I just upgraded a couple of my ZenPhoto installations and followed your "Upgrade Instructions" located: http://www.zenphoto.org/news/installation-and-upgrading
Everything worked out great...except the instructions did not say anything about noting your "Thumb Size" and your "Image Size"...because when you upgrade ZenPhoto it puts all of those settings back to the ZenPhoto default. It wasn't a big deal, had it fixed in no time, but it would've been nice to have seen that somewhere, that way I wouldn't have had to visit the site to discover that my gallery images were the wrong size.
Just a suggestion
Thanks,
Josh
Actually, this should not happen. Anyway, there is no such "Zenphoto default" as each theme makes its own choice as what these sizes should be.
It could happen if you changed the database prefix--then in essence it would be a new install. It would also change if you changed themes and the new theme was different.
Thank you both for your reply, I created the themes along time ago, so maybe there is something in the theme itself causing the issue
Thanks,
Josh
