To post the ad in the "empty" space you'll need to add it to your custom sidebar... I don't really know anything about your sidebar since I never used a sidebar mod but somewhere you can add it like you did the other advertisements presumably.

To get it lower on the page a "quick and dirty" way would just be to add multiple blank lines <br /> in the HTML to push it down as far as you need.

Rounded corners is a CSS trick, I don't know the details personally but you can find lots of info if you google for "css rounded corners"

The image for each category there is a mod for that: https://vborg.vbsupport.ru/showthread.php?t=179596

HOWEVER in my opinion it is easier to just add an <img> tag to your forum description in forum manager for each forum.

So go to forum manager, edit the forum of your choice, and before your description text add something like:

<img src="/images/yourpic.gif" border="0" align="left" />

Customize the path and file name to your needs.
