Occasional bird snapper
See my post above, there are plenty of the very best pro bird snappers that only use a small piece of text on their web images (usually on the bottom) so the statement that you will not see a pro doing it is just not true. Most people do not put text on their images as an attempt to stop people pinching them rather than to let people know who they are or to advertise a web site etc..More or less what I was implying. A copyright which allows the image to be cropped to avoid it is in my opinion useless.
If anyone is paranoid about having a low res web image 'stolen' then the easy answer is not to post on public web sites. Posting images with 'crap' text all over them is pointless IMO - better not to bother at all.
These days I reckon the chances of anyone having a low res image stolen on the web is probably less than one in umpteen million On Flickr alone there is 6 million images a day uploaded and you would be hard pushed to find even one with big text
