Normally I save - (copy/paste) webpages in details view of a particular node for reference purposes.
When a image / object is linked in the details view (html code written to show image in the page) then the image is only linked and never saved in the local mm file when the map is saved. The issue is that during the course of time the website where the image has been uploaded change / delete the image. So we end up with inconsistent map where the data is correct but the image is different or missing.
There should be option to download the images from the page to the map file when we save the map. Just like the internet browser download the images when we try to save the web page to local disk.
