Yes you read right i have searched and searched and finally found a mod that allows you to use HD skins in smp which to those who have thought there skin could be a little more detailed then rejoice, but don't get thrown of by the thought of "oh no its a mod this will be impossible for to do" don't fret it is EXTREMELY easy to install and requires no other mods to use.
the link to their forum post is
HERE: http://www.minecraftforum.net/topic/497537-128x-%E2%98%85-vondoomcraft-hd-skins-%E2%98%85/
they have easy to follow instructions and display sample skins (which you can download) on there forum post and website.
NOTE: in order for people to see your skin they must also have the HD mod.
