I was using Print Screen and the Gimp to make screenies at first, and wishing I had Photoshop's "New From Clipboard" option to speed it up. Once I found out about the {_/-} screenshot key it got a lot easier.
A few things I've found when screenshooting new textures and the prom:
1) When you press the {+/=} key to get rid of all those buttons, the chat is still there and if you hit return you can say stuff without seeing it. This has caused me to say -===wswwwew,.,,,,,...===== and the like a few times.
2) If you use = to get rid of all the buttons in a dance area the dance menu goes away too and you stop doing moves and just jiggle about.
3) If you use = outside the dance area then walk into it the dance menu will appear alone, without buttons and chat, so you can dance properly without as much clutter on your screenshots.
4) You can use the mouse-wheel to zoom all the way in to first-person view while on a dance area where the "1st" button goes inactive, thus getting pictures without the back of your own head in them. The view will be forwards in first-person and revert to previous angle when you zoom back out.
5) Taking a screenshot puts chat in general chat as if you'd spoken, but noone else sees it. This will spoil avatar actions like kiss and hug on your screen but not on other people's and the screenshots still work (possibly only because they happen before the 'chat' does).
