The settings I had chosen for my Public folder might allow anyone to upload/download/delete files from that folder ! ! ! I have changed it now to password-protected. I do not have my photos stored there.

You guys might want to review the Public Folder use in the above link. Several people here have some protection on their public sites, some have none, some are Passworded.

If someone posts a picture from their un-pasworded Public folder and you choose to view picture in another window, in that url you can remove "picturename.jpg" from the url, and then reload the window and you will see all the files in that persons Public folder. Then it is possible to have your way while in there -- DEPENDING on the level of security chosen by the owner of that site.
