Is there a way to prevent users from saving images when they do a save as?
I have already disabled right click in the pages using javascript as well as adding the following header:
<meta http-equiv="imagetoolbar" content="no" />
But if I go for example in OPERA and do page -> save as -> html file with images all the images will get saved. IS there a way to counter this?!
No, there is not. If an HTTP client can download it, it can save it. It is a futile effort to try and counter this.
Edit: Also, I’d like to point out that most browsers allow the user to forcefully (re-)enable the right-click menu on evil websites who try and take that freedom away from them.
