If you find yourself in this situation, you have a few options:
- Video screen share over Skype or Google+ (handy if you're already connected using one of these, but Skype charges for that now, and you probably weren't already using Google+)
- Take a screen shot and email or otherwise fileshare it to them (thus filling their inbox/Dropbox/etc with an image they probably don't want to keep)
- Save an image and post it on Facebook (but your other 814 friends probably don't care to see it)
Here is another- and, I posit- better way to share a simple image of your screen over the internet.
Step 1: Screen Size
Step 2: Screen Capture
You may not get any feedback, but the screen of your laptop is now on your clipboard.
Step 3: Go to Pixlr
Pixlr has three different workspaces: editor, express, and o-matic.
We want Pixlr editor.
Step 4: New Image
In the "New image" dialog box, adjust the Width and Height parameters to equal or greater than your screen resolution, as determined in step 1.
