Web 2.0 Tool Review: Compfight!

Name: Compfight
URL: http://www.compfight.com/
Type of tool: Productivity
Description: Compfight is a search engine for finding images on Flickr.  Compared to searching Flickr with its built-in serach engine, Compfight has a number of distinctive differences.  Perhaps the most noticable difference is that, upon performing a search, Compfight loads many more images to one webpage than Flickr's own serach engine.  Flickr loads 21 thumbnails per search results page, while Compfight loads more thumbnails than I was willing to count. 
Here is a screenshot of search results within Flickr for images tagged "squid":

And here is a screenshot of search results for "squid" using Compfight:

The Compfight search result page may take a few moments to fully load if many matches are found.  The image thumbnails are unlabeled, allowing more thumbs to fit on the page.
Compfight has several search options.  The first is searching for tags or searching for any text.  The second option is to search within the Flickr Creative Commons, within commercial images, or both.  A third option allows you to choose to show or not show original images.  I guess "original" means images made originally for Flickr.  I didn't see any explanation for what this means.  There is also a "safe" mode to filter out offensive images that is switched on by default.
What to you need to know to use Compfight?:  Compfight is an image search engine.  If you can use Google you should be able to use Compfight.
What to you need to have to use Compfight?:  Compfight requires a network connection and a webbrowser.
How do you use Compfight?:
1) Navigate to www.compfight com.
2) Choose your search preferences (e.g. Commons, commercial, etc.).
3) Type in your search term, and hit "enter."
4) Scan the photo thumbs found, and click on the one you want to use to enlarge the image.
An educational use of Compfight: For a biology teacher, probably the best use of Compfight would be searching for images of biological specimens, (animals, plants, fungi, etc.).  As with most search engines, I found that I got more biologically relevent results if I used scientific nomenclature.  I found more photos of actual squid specimens if I seached for "Loligo," which is a genus of squid frequently used in college bioogy labs, than when I searched for "squid." 

Here is a screenshot of Compfight search results for "loligo":

As you can see in the screenshot, there are considerably fewer search results for "loligo" than for "squid" (not surprising), but the images are much more frequently photos are real squid specimens,  as opposed to squid artwork which isn't of too much interest in a biology class.
I am in the practice of using Google Image Search when I want to look for images of biological speicmens.  It does appear that Compfight gives more search results to choose from than Google.  For students looking for images to use in a report or presentation (e.g. a presentation on squids), the instructor could point to Compfight as a resource to use. 
What are the advantages of using Compfight in a teaching environment?: Compfight allows you to quickly locate a large number of high quality photographs, including photos of biological specimens.
What are the disadvantages of ising Compfight in a teaching environment?: Compfight only searches Flickr, and Flickr is mainly limited to photos, not graphs and diagrams.  When I am teaching biology, I frequently search for simple diagrams and graphs to illustrate certain points, and this tool is of very limited use in finding images of graphs and diagrams.
