i've got a few questions a while back on what i use for screenshots for my blog as well as for other areas (documentation, etc.). i know there are a lot of popular programs out there, namely snagit, but i settled on a recommendation from scott hanselman and have been using winsnap.
sure in vista, there is a snipping tool, but i've not found it to be as efficient as winsnap which is smaller than paint.exe in size!
i recently started using the latest version of winsnap and figured i could integrate my other photo tool of choice (flickr) into the mix. for me, the screenshot thing has always been a multi-step process: take the screenshot, save image, upload to flickr. well it dawned on me that i could use the same command-line interface that i use with flickruploadr and integrate that into winsnap...and boom, two clicks to heaven.
here's what i did...first use winsnap -- it is awesome. it's light and fast. it has subtle, yet effective post-shot image manipulation that you can use. i keep it in my system tray and run on startup. i also make the default screenshot be a "region" so i can precisely capture what i want. the latest version also does vista aero glass well.
first for flickr you need to install flickruploadr and ensure you authorize the application (read: run it once and upload a picture to your account). in winsnap go to the tools...customize option. basically create a command like this:
then basically when you take a snapshot, you can change the settings then hit (in my case) ALT+3 and my flickruploadr window comes up and sends directly to flickr. sweet.
if you do a lot of screen captures either for your blog, bugs, or documentation, check out winsnap for sure...it's great.
