Thanks for the response.
Lol...it's you who should be getting frustrated with me, as I know I'm being vague. With a programmer, I'd obviously have to fully explain my concept for them to have the chance of any implementation.
Again though, I'd love to try and make is a plugin that works within the confines of iPhoto/Aperture interface, adding perhaps an icon in the left bar under the faces/events/photos/locations. That would be the ideal solution for it.
Doing searches on web for plugins, most are concerned with exporting, adjusting or filtering the actual picture. My idea involves none of that, merely a way of pictorially viewing the structure of content already there. It would also need to have some drag and drop capabilities, essentially at the faces interface. I repeat though, this is not about individual photos, but about the visual representation of data already input by users that iPhoto's uses to create its groupings like the faces page.
Damn...I think I just muddied the waters more!
Once I can establish if its possible, I will then be on the hunt for a competent programmer.
