navigations?

hello.
here's my probs.
i cant install the navigations picture [home/calendar/gallery etc3]
they're also aligned to left.
i just changed the theme from invision to pbb2 and when i try to install the picture, the 'home' text did not disappear and the picture became smaller right besides the text.
what should i do?

To just have images on your navigation bar do the following.

Display>Pics management
Advanced mode
Change the images there

Display>headers and navigation
Display only images in the navbar : :Yes
