Theme under Gallery Embedding

I have managed to get Gallery2 and WordPress 1.5 to work together. Right now the integration is a manually sync’d but I can pass users between WP and Gallery2 which is what I want..

Which leads me to my issue. As part of the ShadedGrey template it draws a line between the Main and Sidebar which is perfect under WP, However under Gallery I do not want a sidebar anymore and I cannot for the life of me get rid of the damn border!!

Can one of you clever eyed wizards have a look at the following URL and suggest how I could get rid of that pesty line!!
