I'm not sure this will answer your question, but this is what I did. I ran into this problem some time ago. So I started making a separate folder for each category. A sub-album for personal (family photos and the like), completed projects, jigs and fixtures, general woodworking, etc. Name them whatever you like and something easy to remember when you start to look for a particular photo. For example, if you made and end table, you might want to put it in a sub-album titled "furniture". Or an adirondack chair or bird house might be in "outdoor projects".
I would go ahead and reorganize them now before you get overwhelmed with photos and edit the links that you remember. It's not going to get any better. Don't worry about those that are posted in various forums. If someone clicks on a link that don't work, and they really want to see it, they will usually post a reply that a link don't work. When they do, you can edit the link then.
Hope this helps.
