I'll have to look at the settings, this is probably something that can be adjusted in the back end. As for images with broken links, there was a migration of our 4 yr old database from the old software to the new site and for the most part everything transferred very well. If you see broken links you should try to edit the post because in a lot of case the info is still in there but the software is just unable to display it. By editing you can correct the issue and a lot of times it will fix it.
HTML will often be at the heart of the problem because our new software doesn't allow HTML in posts as it can be an entry point for hackers.
I believe there is a photo gallery add-on available, I'll have to look into it and see about having it installed here.
Thanks for the comments, I'll work on it.
