Picassa.
As described at Download.com here; http://download.cnet.com/Picasa/3000-2193_4-10160334.html and have a look at the features explained in the video on that page.
What I am not at all sure about is your requirement for a free hosting web site service, if that is what I understand you also need from your list above. There are many free to use online image hosting services, but for multiple uploads they may all require registering.
It seems Picassa is now owned by Google and this link tells more; http://support.google.com/picasa/bin/answer.py?hl=en&answer=93773

Hello,
I'd really appreciate any help, information, advice or even offers to get involved in an urgent project.
To put it simply I'm looking for "off the shelf" software to link to a web site that will allow the following:
1. Users, without any pre-registering to upload their photos and a message into a hosted online template.
2. Allow a preview of the photo within the template to be viewed - with basic crop/zoom in and out of the photo within the template.
3. Allow then the person uploading to tick an approval box and the the photo and attendant details are entered into a database.
4. There is no requirement for the person uploading to see their photo again and they should not be able to view any other photos that have been uploaded.
5. There is no requirement for payment processing, but would need to link to an established portal.
6. A nice to have would be a profanity filter that would scan the message.
This is 100% genuine and may even present a work opportunity for someone.
Any software needs to be able to handle large volumes, its totally legal and sports orientated.
More detail can be supplied.
Thanks
