*cough cough* I remember someone suggesting this a long time ago and even offering to help maintain it! Hey, I'm just glad we got a new look I had been pushing for, LOL!
There are ways of doing this and running them directly from the Nest's server. Where people can upload and copy and paste just like they would on photobucket or something similar. Might have to change carriers though. The one I'm most comfortable with costs $20 a month for unlimited bandwidth, server space, and even an online store.
In the meantime, contact the person that created the post and have them fix their images. Usually this happens when someone starts organizing their photobucket accounts, lol!
