I know about the whole "www.minecraft.net/skin/USERNAME.png" thing, but that's my old skin. I changed it recently and went through the process of logging in to the Minecraft site and uploading it and changing it and stuff, but now it's not there… It's just my old one. Is there an alternative location where I can access it the re-upload it to the minecraft.net server?
Where is my Minecraft skin located?

You can directly edit the default skin in the minecraft.jar. Others won't see your skin in multiplayer though. There also might be delay in the skin update. There's also a possibility that the file you try to upload as a skin is either wrong size or format and is not valid.
