How to turn this transparent?

[Portuguese]

How can make this background transparent?
Can you do that for me if that is not too much trouble?
It is just a simple star, so it must be just a minute to an experienced person...
(PS: I have not installed any program, but I have PaintShop Pro ready for reinstallement, after my last PC format)

This should work.

Here is another version - I personally hate the white fringe that's caused by shading, so I removed & touched up a couple of areas:

To do so yourself - PhotoShop & PaintShop are fine. The method I use is as follows:

Load image.
Load new canvas with transparent background.
Cut & Paste image onto transparent background.
Delete excess areas (may need to zoom in on the image, especially for tiny images like this star).
Touch up where needed (basic paintbrush/eye dropper methods).
Save finished product as GIF or other compatible file.

Thank you very much.

This is quite new to me.
As I am finishing my degree (Economics), I plan to study a bit this kind of things soon enough.
I plan to even do some units.

Again THX for the very good job you've dome here
