How to capture an image of a widget
Go to any dashboard or web report, hover your mouse over a widget, and click on the ellipsis "..." located in the top-right corner. Then, click "Share”.
The drop-down menu will then display 2 options: “Copy” or “Download”.

Download - This will save the image to your computer. The screenshot will be saved as a PNG image.

Note that the "Copy" functionality is only available on browsers that support clipboard API (for example, the Chrome browser supports this).
Using this to capture a textbox image? For your screenshot to include images inside textboxes, the textbox images must come from a source that has a supported CORS header. Imgur is an example of an image hosting service with CORS support.
