Your code is working very well, thanks.
Just one question!
I want to paste an image by pressing ctrl+v or hitting button, but i don't know how to trigger your paste event after hitting the button.
I tried everything but none of them worked.
plz HELP!!

You can't trigger a paste event for the user other than through direct user interaction (ctrl+v, context menu 'paste', or dropping content). It's a web security issue. There may be a way for your page to request additional clipboard permissions to allow for script generated clipboard events, but I'm not sure of the details.
