I'm using the default template with square thumbnails so I'm using a lot of custom crops. I temporarily tried out another template and all of the custom crops disappeared once I switched back to the default template (which makes sense now that I think about it).
Are the custom crops saved in the database? I have a backup of the database made after the last time I uploaded photos. If I restore the database using the September 20th backup, will the template, custom crops, and all images be back the way they were that day?
