Image insertion plugin

Hi

I’m a newbie in WordPress. Currently, I’m developing my own theme where I’m stuck now. I would like to insert some images into multiple divs on my website. Ideally it would be cool if I could configure which images that are inserted into those divs from within the admin panel. I’m thinking of a plug-in which allows me to define some image containers which then could be used in the page php somehow like

<?php ImageInserterPluginInsertImageNo(4) ?>

This would then insert image no. 4 (which would be defined in the plugin) into the page. Does anyone know if something like this exists? Thanks for your help!

Cheers, Christoph
