Board Thread:Support Requests - Designing Your Wikia/@comment-11706253-20140726151536/@comment-4399679-20140726161612

Simply downloading the file shouldn't give it a permanent white background. Try to download the image from, and set it as your Wordmark via Special:ThemeDesigner and it should just blend in with the background on that Wikia.

If you absolutely can't figure it out at all I'd be happy to do it for you if you would like. (I would need temporary admin rights for about 2-3 minutes.)
