I made a little plugin to show on the community member profiles the images they uploaded to the Hot-Or-Not Factory.
You can see it in action here:

See the tab named 'Disenos' (the site is in Spanish, and features a highly modified Hot-Or-Not Factory, among others.
For the logged in users on their profiles there an extra link from where they can upload new images. Although the above site uses a modified version of the component the plugin works with the component out of the box - you don't need to hack anything ;)
The Community Builder plugin can be downloaded for free (you need to register!) from here:
