Paste a cropped screenshot (image) from clipboard

Setting up a kind of social ‘wall’ or timeline, for a news site, I want to be able to save time by pasting a cropped screenshot from my clipboard.

To be clear, my process is to copy a cropped screenshot, there is my image. Then - rather than having to save the image, then to navigate to it and to upload it - I just want, quickly, to paste that cropped screenshot image (into a MIGX tv).

…This process works, for instance, to paste screenshots to various social networks, and saves considerable time when posting many images on a daily basis.

I note that by using a rich text tv I can paste a copied image but not a cropped screenshot which is what I need.

Can you specify more precisely what you mean by that?
Is that a functionality of your browser or a browser plugin or some OS functionality?

In what format is this “cropped screenshot”? Usually an image is a binary file, a richtext input expects text. There are ways to store an image as text like a base64 encoded image.

What do you mean by “copied image”? Using Ctrl+C on an image file in a window of the OS?
What richtext editor are you using?
