Pasting Images to web pages

I am trying to find out if there is a way to paste images to web page forms much like you can paste text.
The reason being is we have a web based help desk site and users submit issues using a form that we made.
We would like to be able to have them send a screen capture of an error they may be getting using the PrintScreen button
but without them having to first save the image using an editor like MS Paint and then uploading it using a a regular file upload button normally used on a webpage. We want to make it as simple a possible for the users. Is there any way to simply paste images from the Windows clipboard into a form at all? I hoped there was some sort of code that would allow for this.

Thanks in advance,
Adam
