Hey. I’m working on a website that is really image intensive, too, but I’m not migrating mine. I’m starting over. I also don’t know if a gallery is a good solution or not. I am an artist, so I’m uploading lots of artwork. And I mean lots. I am uploading them each as image posts so that I can utilize common WordPress widgets like Newest Posts, and make use of things like categories, tags, and dated archives. Think of how blogs organize their content, then imagine using a format like that for your images. I love the idea.
Why are you worrying about keeping HTML in the name? WordPress pages are built using PHP, so they will actually have a .php at the end instead of .html. Most people don’t worry about that, as WordPress organizes everything into folders.
For example, instead of migrate.com/my-sketch.html it would simply be migrate.com/my-sketch/ (the full path would be https://migrate.com/my-sketch/index.php) so it makes for much cleaner paths that are easier for people to remember.
You could utilize something similar to what I’m doing, with categories. If your sketch is, say, a mustang simply titled Mustang, a path could be migrate.com/sketch/mustang
Hope that’s helpful. Best of luck to you.
