Why can i only have one skin?

[imk]

ok my site is www.whoyoureppin.com

i have these images in some threads on the forum home in colums and i think that may be the reason when i upload another skin i get this


If you look at Vol.2 in styles you can see it better, its where the last thread bit is etc, is there an edit i can make to those forum templates to get it back to normal like in vol.1?

or can i only have one skin due to these images?

thanks in advance to any who helps.
