but if i have images with 100X40, it can be very slow :(

To make it more clear: I have checked the id of the items. Note 2: I wanted to create buttons with icons, but now I realize there is possible to create tool bar, but I would need the toolbar be extra small and not to be moveble, but fixed on a page. Note: the icon is not standard size, it is 13x13 It is transparent ico (normally displayed in explorer in Windows).
