Hmm, I should actually make it even better and add an RSS feed to your own images, or you can use the API to list the latest ones and download the ones you're missing (no need to keep redownloading everything every time).
Also these would be authenticated, nobody should be able to discover which images you have uploaded. The RSS feed and API listing would be for you only.
I guess I'll sign up next time I would have uploaded to Imgur. Thanks.
