[SOLVED] PNG image with transparency not displaying correctly

So I saw that there is another post with this same problem but the solution suggested in that post (changing the Image style options) did not work for me. I'm still getting a white background instead of a transparent. Tried displaying the same image in a sidebar and it displays correctly.

Here is a link to the page. Any suggestions are greatly appreciated.
