YM, if you do something more creative than just a site where you can browse through the images, than yes, I'd say that's a good idea.
Perhaps categories for certain styles of detailing, or highlights of specific types of detailing. Something like that. Make it actually more useful than just screenshots and take advantage of it being a website then I think it's a great idea.
Otherwise, no, I have the folder that contains these screenshots favorited in the side bar of my file browser, so a bookmarked site would not be much more useful.
