Forum:How can I upload/make my own wordmark?

Every time I try uploading a wordmark, it tells me that it's an invalaid file type. I really need help! Also, check out my wiki - (www.macys.wikia.com). Fortress Swan  16:29, November 22, 2012 (UTC)

 * Well, I saved it as "Wiki-wordmark.png", however, it gives me this notice now :
