There is a lot of old and new law that may apply.
New laws were drafted for the Internet and may well be applicable world wide, but I'm no lawyer.
It is called Deep Linking! The essence is that you are allowed to place hyperlinks on your website provided that they are to either the other sites 'Home Page' or to a main page of the site, but Deep Linking is prohibited.
A Deep Link is a hyperlink that places/displays part/pages/pictures of the other site on your pages as if they were part of you site.
I think a link that displays a picture off a ladies AW website in your post would I judge to be Deep Linking and so an offence. The usual first recourse is to contact the webmaster of the offending site and ask for the removal of the offending content, failure to do so could then result as a trip to the courts, with all the associated costs.
The other side is an issue of copyright, which can be a complicated issue but a starting point is probably that someone, somewhere, owns the rights to everything on the Internet, save if it is over a certain age.
The copyright of pictures may lie with the photographer, the model or some other third party.
So to use an image without permission can result in legal action, the starting point to be contact the webmaster of the offending site and ask for the removal of the offending content, followed by the court route.
So if you download an image off AW or make a copy of it and then use it in a review, it is likely that you and/or the owner of this site you are in breach of someone's copyright.
Deletions;
AW deals with profile images in a convoluted way as far as I can work out. Normally when a lady uploads a photo or other content onto her profile you would expect them to be stored in a folder on the AW server with the other data files of that profile, then if the lady deleted their profile all the data file would go with it and therefore break the links in your review and images would disappear and leave this icon in its place;
Hidden Image/Members OnlyHowever the design of the AW site seems to locate the image file in a more distant place and deleting the profile deletes the pages that are displayed so they are not available and do not get displayed.
However with the AW method the pages disappear but any images that are Deep Linked to in these 'remote' folders will continue to work and display, until the AW administrator should delete, move or rename the said location.
I hope that this makes some sense and I repeat it is only my limited experience and I'm no lawyer.
