Images for flash help please

Hi everyone,

i’m new to the forums and had a question that I have been trying to figure out for awhile.

I’ve seen many flash animations/intros where there are images that look like its on their own. For example a floating balloon. How do you take an image from the web(right click save) and strip it down to just the object in the image you want?

I know this might not be done in flash but since we are all flash users, i’m sure someone has experience in doing such things.

Thank You
