windows 7 - Capture region of website/etc. to clipboard as image?

I often need to capture a fixed portion of my screen (typically in Chrome) to the clipboard, for posting as a background in a PowerPoint slide.

Question

Where can I find an extension for Chrome or an app for Windows 7 that can accomplish the desired (below)?

Desired

1. Select a region for storage in the clipboard.

Undesired

But because I cannot do that, I need to:

1. Capture my screen via 3rd party software.


2. Save the captured region as a file.


3. Paste in the image.


4. Crop the image.


5. Clipboard the resulting image.
