tabstrip graphics

I believe it's possible to do the following but I'm not sure. I want to load a graphic or different "design" into my IE Tabstrip control for the tabs. How would I do this and where can I find some free graphics??

<IEWC:TAB DefaultImageURL="images/StatusTabs/Tab_Inop_Unsel.gif" HoverImageURL="images/StatusTabs/Tab_Inop_Sel.gif"
SelectedImageURL="images/StatusTabs/Tab_Inop_Sel.gif" />

i found a tab i liked - altered it with photoshop, made 2 states (hover/selected and unselected) then used as above

images.google.com - used advance search for small gif
