Preview URL pasted image which was not uploaded

[rasos]

We have been promoting not always uploading images but also just to paste an image URL. This saves disc space and is the preferred method if copyrights are not cleared.

However, the ep_previewimage plugin is not intended to be used with ep_image_upload anymore
https://github.com/JohnMcLear/ep_previewimages/blob/master/README.md

So is it intended that the function will be integrated in ep_image_upload, showing images for which we only have an external image URl in the pad? Currently, no image is shown, if I add an image URl into the pad.

This would be very easy for someone to hack into this plugin.

It would just require Dom line processing and some test coverage.
