Make a club logo transparent??

I am trying to add new logos to the newly promoted sides in the Skrill North/South which are Cambridge City, Weymouth, Wealdstone, Buxton, Bury Town and Whitby. I want to be able to make the logos transparent which means the white background of the image cannot be seen.


Also is their any way to make the name of the team be straight under the other team for example:

12th Stalybridge
13th Whitby

NOT LIKE THIS :(:(
12th Stalybridge
13th _Whitby

Any way I can make a space or anything so that the teams are level under each other?
