What is “hotness”?
When a photo is submitted to a photo challenge or theme, the photos that the community likes best become “Hot.” Hotness is determined automatically by factors including number of votes, comments, views, and favorites. A photo’s hotness is not permanent, but can change based on how the community is responding to other photos in the theme, and we recalculate hotness daily. That’s why even if nothing changes on your individual photo, its hotness could change based on the popularity of other photos within the theme. On the JPG homepage and the first page of any particular theme, we also show a selection of the hot photos in order to highlight the best photos from the site. The photos that display on these pages are pulled at random from the hot photos that we have selected to display. Hot photos also have a banner that links to more hot photos within the theme, along with tools that make it easier for other people to promote your photo on sites like Digg, Facebook, and StumbleUpon.
