In Flash, the white box you see on the workspace isn't really there. You can set the background color of the Flash movie so you don't have it against a white background (probably have to find out what shade of gray this forum is using. Looks like it's #222222.
Wouldn't it be easier to export as a GIF? Just color the background something like magenta so you can set the GIF's transparent color to that, making the background transparent. I don't recommend making white transparent since that one guy in the cartoon is also white, so he'd turn into a dark gray guy if posted here.
Of course, it would have taken less time for me to just make the background transparent as opposed to writing this.
So here you go.
EDIT: Would have been if it weren't saved to .JPG. I think I'm reminded now why we should start sending PNGs when the images are simple: PNG allows multiple levels of transparency. GIF only allows full transparency, so the border has to look blocky or else you'll get white spots around the edges. PNGs would be great for Flash images since Flash is just vectors that ends up as anti-aliased lines.
I remember Face. Good times. Good mocking-Face-because-I'm-way-older-than-the-target-audience times. I did like when he mimicked a frog though.
*looks at comic again* We don't have enough images of people getting childhood memories scarred. I'm pretty sure there are similar comics involving Big Bird... oh, duh, the picture of Big Bird served up as a Thanksgiving bird.
