Trouble with image display in IE

Hi,

I certainly need some help with tihis cause it´s getting me crazy.

I´m redesigning my page and doing quiet well, no tables, css etc. At the right side of the page there´s a menu and if you hover the links yo can see at the bottom a description of the link.

Works fine in ie an mozilla, so I decides to include as well some images from sites of friends which I´m helping, further down of the menu yo see a title
