In order to make the separate parts into transparent GIFs, we'll need to clear out all of our white space until the parts are floating on a transparent background. Most graphics/editing programs have a magic wand tool, which can automatically select an area based on color fill; they also have a "contiguous" option or something similarly named. When you select "contiguous" areas, it means that the area selected won't break past any line boundaries. In Photoshop I used the magic wand tool with the box next to "contiguous" checked and a tolerance of 32, and then clicked to select all of the white space outside of Lex's parts before deleting it (the checked background in Photoshop denotes transparency/a blank canvas with no fill). I don't want to delete the white areas inside his eyes and shirt, which would happen if contiguity was turned off.
If your linework isn't clean, you may have problems getting a clean selection and may have to take an eraser and go back to clean off a few remaining white pixels here and there.
