Let’s face it, Flickr is kind of inconvenient when it comes to photo browsing. You type a keyword and hit search, Flickr by default returns results of 24 images, one after another, top-down approach. If the keyword returns more than 500 results, imagine how many pages you’ll have to go through.
CompFight is a Flickr image search tool that makes searching really simple. It displays in thumbnails, leaving the photo details behind. My 1280×800 resolution displays at least 50 thumbnails at a time. Next few batches get loaded while you scroll so you don’t have to click on the pagination. CompFight is limited to tag searching only, perhaps the only limitations I see.
