Depending on your browser, there are bookmark manager add-ons/extensions available that allow you to create bookmarks with a thumbnail of the page. Or to add your own.
For the hell of it, I literally just now added 'Visual Bookmarks' and tried it out. I don't normally use a browser 'homepage' that includes images; I use a dropdown text list. Regardless, I made a "ZoneGfx Wishlist" bookmark folder. I saved the bookmarks as usual. Voila! I have a single page (like a browser homepage) filled with thumbnailed bookmarks.
I didn't like that it used the entire page as the thumbnail. So I copied the product image on the ZoneGfx page, and edited (pasted it to) the bookmark. Fixed. It's certainly not as simple as ticking a box on the webpage, but it's close.
I don't know if I'll keep this bookmark set up, but it looks good and works well. Thanks for inspiring the idea.
