How to copy and paste a picture found on the web to wordpress easily

Anyone knows how to do so? What about if you want to edit the pics a little bit before pasting.

I am using windows.

It should not be a lengthy process.

Straight from the web:

1. Right click > Copy image location
2. WordPress: Add Media > From URL

Editing a picture:

1. Right click > Copy image
2. Paste into your favorite photo editor (e.g. GIMP)
3. Edit and Save
4. WordPress: Add Media > From Computer

Note: with WordPress 3.3 you can also drag-and-drop files.
