How do I change the backgrounds to transparencies?

In GIMP, how would I go about changing the background of a sprite sheet to transparent?

Moved to QIT.

Hold one five minutes while I whip up a quick guide okay??

You may want to skip step 2 if step 3 always occurs! You may be lucky and might not be required to do 3+4, though.

Right-click on the layer you want to make transparent (if you opened a PNG or whatever straight up it'll be the only layer). On the right-click menu there should be "Add Alpha Channel", if it isn't greyed out (meaning that it already has an alpha channel) click on that.
Click on the Select by Colour tool (or Shift+O) and go to Tool Options to set the threshold to 0. Then click on the sheet's background to select all of the background (a properly made sprite sheet shouldn't have any other content with the same colour as the background). Tap delete on your keyboard and you should have a transparent background.

Ah, thank you so much! I tried following some super-complex tutorial that didn't even work in the end, when it was this simple! Your method works like a charm!

Do you think you might be able to move this thread ---> http://www.spriters-resource.com/communi...?tid=20979 as well? I'mnot sure how, but I missed the QIT category, so I posted it in Models Projects >.<

And this method works too! Thank you!
