For any image, for example, on photobucket,
is there a way to make images more, erm, transparent against the background? Like fade-ish?

Or maybe to make the image's periment kind of seep into the background.... XD Idk.

.....any help? x3 I've tries the erase tool... but it just makes those areas appear white >__>;;

Help would be much appreciated, actually x3

EDIT: K, here's an example. With this image, I want those white parts to be the background color.... transparent... I did the eraser tool, but it didn't work ;_;

EDITEDIT: another example c:

Help? ;-;
