How difficult would it be to code an ActiveX control to retrieve an image from the Windows clipboard if the control is embedded in a webpage? For instance, the control appears on the webpage as an image box and when the user right clicks a menu pops up allowing them to paste an image.

I'm confident I can write the code to grab the image and display it, but how would I go about creating the control, embedding it into the HTML, and then capturing the data that composes the image so it can be stored on a webserver?

I can't find any good tutorials on how to do something like this.
