IE dont show images in header widget

Hello.

I made four header widget (cells=4). And if i put an image into two first widget then
Mozilla firefox shows everything perfectly but IE won't show - image in the second widget is not visible wholly.
Second image is 728px.
If ia made two header widgets (cells=2) then these two images are not side by side. It seems like the second images starts from 3-st cell/column..... Even if align is 7 (left bottom).

Hope you understood my problem and can help me to solve this.

(And sorry for my not so good english).

Thank you.
