It's not quite 'Explored' but it's a foodies version. Foodgawker publishes selected photo's from food related blogposts. So far 9 of mine have been chosen for foodgawker.com/ and these are shown above.
It's quite effective in driving viewers to a blog. 2500 people alone have clicked on my picture of Hasselback potatoes and gone to the blog page on thingswemake.wordpress.com/
All photos must be square, less than 500kb and have a blog post link, which limits it a bit. I have had many more rejected than accepted.
