Free screen grabber for OS X I'm looking for an app that lets me capture a rectangle, puts it up to an image bin, and puts a link to the image into my clipboard.

Dropbox does this, with one problem: it doesn't link to the image. It links to a page containing the image, but it isn't trivial to extract the image from the link.

The reason I want a link to the image is because I use IRC, and most good IRC clients are smart enough that if I enter the URL for an image, the other users of the channel Will see the image. However, if it is linking to a page containing the image then that is no good: they will just see a web link and they will have to click it, and it will open up a new browser window, and that annoys people.

I've also checked out Jing which is very nice, only it suffers the same problem.

EDIT: I started writing a script https://stackoverflow.com/questions/21371254/osx-automatically-upload-screenshot-to-imagebin-and-put-url-in-clipboard

So far it uploads file, puts a link into the clipboard and make some noise. Can anyone finish it off?
If you have ssh access to some server, you might use a script like this:

f=$(date +%Y%m%d%H%M%S).png
screencapture -i ~/Sites/upload/$f
printf %s http://example.com/$f|pbcopy
scp ~/Sites/upload/$f user@host:public_html


To make scp not require a password, run ssh-keygen, accept the defaults in every step, and then run ssh user@host 'mkdir -p ~/.ssh/;chmod 700 ~/.ssh/;cat&gt;&gt;~/.ssh/authorized_keys;chmod 600 ~/.ssh/authorized_keys'&lt;~/.ssh/id_rsa.pub.
