Frontpage with images
You're saying you want images from another site? I've got two pretty basic suggestions...


build them into your theme. You'll want to create a div (or three) in a template for the front page, adn then you can add them in with css pretty easily.
display them with a block. Create a new block, make sure you turn on HTML for your input and then add your images:




Enable the block for the region you want, and tell the block to only display on the front page. You'll want to do some simple css theming to that block, as well, to make them look how you want.

Both these options are just to display images. What do you want to do after that? Will clicking them take the user to another page?
