See Changing Background Color 1. It uses the Color to Alpha plug-in.

But the quality of this image is as low as its complexity, and I think you should just make an new one.

thanks. I was thinking about making new one but was not able to make the damn triangle in the middle – Omnipresent Oct 2 '10 at 12:52
Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – Oliver Salzburg Feb 6 '14 at 18:57
The described <context menu> -> Filters -> Colors -> Colors to Alpha item mentioned in the article (under Step 1) does not appear to be available in GIMP 2.8.10. – Peter Mortensen Feb 13 '14 at 9:36
