Image Moo - Image manipulation library

yeah it is great for social media sites where you need the thumbnails to be the EXACT same size, like 60x60 pixels for instance so they can line up neatly next to eachother. alternatively you would usually just maintain the aspect ratio (width, usually) and it will mess up the page's layout significantly. i can grab the code from one of my projects soon and post it for you.

what it does is resizes it to 60x while maintain the aspect ratio of the longest dimension. after that it takes the other dimension and positions the cropped region in the center of the image. it produces thumbnails that are comparable to facebook (really, i have compared it with facebook's automatic cropping and the images almost always crop at the same spot so i am sure they are using a similar algo).

i'll unzip this big archive (like 50gb, its an entire social media application i wrote with the whole database in tact, around 150 thousand users, so it will take a fair bit of time) and find the library that does it in a moment.
