Sent from my iPhone, using Dock for the screenshot, SendPics to email the full size image, and Flickr to auto-post to my blog.
Some more info on how I’m getting iPhone screenshots:
Screenshots courtesy of the otherwise-annoying “Dock” application. Install it from Installer.app. It puts a little light blurb way down in the lower right corner. When you tap and drag on that just right, managing not to trigger whatever icon is also down in that corner, you get a nice scrolling rainbow “dock” with all of your installed apps. Scroll all the way to the right, and the last two icons are “Screenshot” and “Cancel”. Hit Screenshot, and a couple of seconds later, a screenshot is taken, and added to your Camera Roll with a filename starting with IMG_9000 (I guess so they don’t overwrite existing photos). Then I emailed the non-scaled version of the screenshot to Flickr using the “SendPics” app.
