Well, I could give you the long answer, step by step; or I could just say "I use Photoshop". But if you are interested in the long version. I have Photoshop cs, and do the following:
- Find a decent picture of the preferred character for an avatar.
- Either "mask" the character from the image using the lasso tool (depending on the images dpi, it's best to "feather" the selection for a smooth edge) or painstakingly erase the background from around the character after duplicating the layer image so the background is transparent.
- Create a new Photoshop document (PSD) to the specifications of Muppet Central's avatar regulations, sized 64 by 64 pixels at standard web resolution of 72dpi, RGB color.
- Drag the masked or "cleaned" character from the previous file into the new PSD.
- "Free Transform" the character evenly to size to fit the new 64 x 64 PSD as best as possible.
- Make sure the background layer of this new file is turned invisible so the character's background remains transparent and not white (or whatever other color your default settings are).
- Use Photoshop's "Save for web" feature set to "gif - 128 dithered" with the "Transparency" box selected.
- Save your new avatar to your computer and then either host it on a free picture hosting site or upload it directly to Muppet Central.
For those of you who have Photoshop, I hope this helps. For those of you who gave up after reading step one; fuhgedaboudit' and just post whatcha' want and I'll do my best to take care of it.
