Here is what a photographer's release will generally look like. As Chip stated, it protects the photographer - not the model. The release give the photographer unlimited right to use the images he/she takes without restriction, for commercial use, website use, publishing etc...http://www.danheller.com/images/FAQ/Business/model-release.gif
Models may wish to amend the contract to say something like "Photographer must get model's permission for website publishing, etc..."
I can't see a photographer agreeing to such a clause however. Why waste the time shooting a model if you havbe to return to ask her/him permission to post a pic?
Every photographer has a website today. A photographer's website is their new portfolio, so I would assume a photographer was intending to use their photographs on their website. (Duh?)
In absence of a specific photo release or contract, the rights to the photos remains with the person who snapped the shots. The photographer will be able to use the photos for personal use but may have trouble using the images commercially without the model's consent.
Another suggestion would be to discuss usage/ model release beforehand so the terms can be clear before shoot day.
For the models -
1 - You are using a photographer's work on your OMP sites and your websites etc... Why wouldn't you expect them to do the same with photos he took of you?
2 - Model's should thank photographers for the free publicity when they post your photos on their portfolio website, perhaps, instead of threatening them?
Have a nice weekend!
