WordPress custom menu items featured images

Hi everybody!

I’m making a theme, with a slideshow in the header. I figured, that the best way, to make the slideshow is to do it like this:

• Get all the menu items that have features image. Outgoing links and posts/pages would be ignored
• For each menu item, the output would be like this:<img src="featured-image-url" href="the-link" title="the-title-used-in-custom-menu">

Hope you understood!

PS: I know that img tags can’t have href attriputes, but thats the best way to get the information for my plugin.
