Site categories sub-site upload high-res site image feature request

I would like to make the following feature request:

Site categories sub-site upload high-res site image feature request

I have Site Categories setup ok at http://tradr.com/sites/

Instead of installing the old Avatar plugin, I would like the sub-site owner to be able to upload their own site image from their backend Site Cat settings page.

Furthermore, I will then be trying to display all sites in a site category on the main site, as a grid of website images.

Here is an example: http://www.shopify.com/examples

Any +1's ?

Cheers,

Johnny
