What is wrong with a page like this?
The image is not transparent.
Images that are transparent tend to make the page look better.

If you cannot make an image transparent it is reccomended to add the Category:Transparency Needed to the image's page so that other people who can make the image transparent can do so, and to make the file type ".png" so that it is easier to update.
