Guide or tips for editing court

Anyone who can help me to edit or create a court. I'm just thinking to create a court in my game but I have a p[roblem. Everytime I try to change the Logo of the court like in FIBA court, the logo in the centercourt changes but around it is all colored white. Another problem is the Logo I change in the centercourt don't completely appear, there's a particular part that it show like in FIBA court, if change the circle by a text logo, the text doesn't show completely, there's a circle and the text inside that circle is the thing that appear in my court. I hope you could help me.(sorry for my bad englis)

BTW i used the IFFEDITOR by showform.. Thanks.....
