In order to remove a theme you should only need to delete the theme from the App_Themes folder and delete the master associated with the theme. Of course you should always backup the site before trying one of my suggestions.
The only images you should delete in regards to the design files are the files in the Design Files directory. I would recommend deleting the photos in the Albums through the web interface. If you just delete photos out of the Album directories, there will
still be file path references in the database.
