moving from /ipb to root directory

[agghanim]

I've just moved from vbulletin4 to ipb3 and on to ipb4. All data was copied over nicely.

I've first installed IPB in a /ipb folder and now moved it to my root folder. Everything seems fine except for the images of my theme. Every image now displays a small square. I can't find anything in admincp to rebuild the theme's cache or input the theme location. 

Any pointers?

After a lot of hours of searching I did not find the most graceful solution.. I copied the missing images back to the old IPB folder, which is just a workaround for my issue. Nowhere could I find the variable that defines the path for the theme's images..
