hah, sorry i was on holidays for a few.

I wrote mine in php just because i had the platform ready and half the code for the database and pic handling etc. Probably not the best choice, but should be easy to integrate in my wow-ratings.com website.

I use 21x21 icons otherwise the resulting image is just too big. i also have all the 43x43 icons so can actually swap from one size to the other by commenting one line.
Same thing with the number of pixels i read, by default i take every second pix, but depending on the size and quality of the original image i can easily go to every, every third, fourth pixel or whatever.

i noticed you'er using a fully black icon for black pixels, I thought about it as it really makes the images better looking, but voted against it as i considered it as cheating ;-)

How many icons do you have? i'm using a pool of about 4600 which i slowly crawled from the armory :/

in any case, here's my result for Seldum's avatar




Cheers,
