Hi, i really really liked your hard work and thank you! i've added you in credits on toplist and contributed as i could!

One question, i wanted to add a custom picture instead of this > http://puu.sh/l4Kxa/a71c0a43bf.png

and add menu items here > http://puu.sh/l4KAO/d78978e2c1.png

Any help? i tried to remove that freesamp.net thingyand it messed the whole orange, so please give me a little hand.
