Some professionals in the field have told me to be extremely careful when posting online and to use a large watermark with 60% opacity (these are 50%). One guy told me a story of how he posted one the web with a discrete copyright logo at the bottom of a picture that was included in his webfolio but had sold to a greeting card company with exclusivity for one year. A calendar company came through his site, copied the image, cropped the copyright and used it in their calendar. The greeting card company some how found out and filed suit againt the photographer for breech of contract. In the end, the greeting card company retracted the suit and settled after the photographer sued the calendar company for stealing his image... he won, of course and even made a small sum of money from it... but all could have been avoided with a semi-obnoxious watermark. I doubt any of my pics are good enough for someone to want them for a calendar, but other things to consider... for example, someone stealing the image of the child and placing it somewhere on the web with some negative connotation attached to it/her and no way of me ever finding out... pro's and con's, I guess....
