Thinking about starting back up with Flickr... it seems useful as a way to show a deeper array of images, maybe get a few nibbles... plus it works on smartphones and tablets nicely, etc.

Having been off it for a couple of years, I'd start a new account. What is the best way to organize your images for Flickr, since they want to order everything by date? I remember editing dates to get the order and sorting I wanted with a set. Is there an easier way to sort picture order other than planning ahead or changing dates one at a time? If I could simply drag and drop to sort it would be fantastic.

Also what is the optimal size to upload? I don't want to upload tiny images out of some paranoia about some Third World rip-off... they already have.

Any other tips? Does Flickr apply sharpening and gamma adjustments without user control?
