I'm generally against the practice of making images difficult to download on websites.
However, we have a number of photographic contributors who grant us exclusive free access to their images.
Not long back I had an instance of a website using a lot of our information including photographs.
What steps can I take to secure our images? I appreciate that it will never be bullet-proof, but I'd like to make it at least mildly difficult.
The likes of a watermark would probably be ideal, but I know very little about the subject.
EDIT: It has just occurred to me, having watched a Watermarking plugin demonstration video, that I need my users to be able to view the image perfectly, but for it to be downloaded with a watermark (i.e. if they right click > save as). Obviously this makes things much more complicated and I realise that the images will be susceptible to screenshotting and
wget, but at least I'll make it somewhat difficult for some would-be image thieves.
Do any such plugins exist, or are there any built-in WordPress functions which might help me out?
Thanks in advance,
