Why is this so hard? I just want to select part of my screen, and then have it be either uploaded to my Facebook in an album (best), or posted on my Facebook timeline as a linked image (acceptable).
The answer might be FireShot, but I don't like the idea of paying $40 just to find out. Or at all. Ever. The free version is great for taking a snapshot, but getting it to upload anywhere is hard, and even if you do, it doesn't make a Facebook photo upload post about it. So it didn't seem like a good place to go.
There used to be something called CloudSave that would let you right-click on images and do this -- and it was great. But it stopped working. And can't do screenshots.
It seems like such an obvious operation to have to take multiple steps for.
