instructables hack: image-grid project browsing index

if you noticed the slideshow project index uses a grid of big thumbnails to let you view the projects. you can use this for regular instructables too! try these links:

http://www.instructables.com/tag/type:id/?layout=images
http://www.instructables.com/tag/type:id/?sort=RECENT&layout=images

the secret is the 'layout=images' bit, appending that to any of the 'explore' url's will show it in the new format.
