What I would do is...Create a new image, any size you want as long as its as big as the size of the image...you should see this little grid thingy on the image, like a white and gray grid, thats the transparency, then paste the logo in there, then go around the logo and delete the unwanted background color, when your done, just use the rectangular selector and when you paste the image elsewhere, it wont show the background
