If your web browser does not support integrated JPEG images on a page, then you will not be able to see the thumbnails. I do not maintain a list of which web browsers support what, but I do know that currently the Prodigy server does not support integrated JPEG images. We use JPEG images because they are the most compact of the popular formats. A comparable GIF image may be ten times the size of the JPEG version. If people allow their children access to the Internet, they are allowing them access to the world.
Most adult oriented sites start with a page that says the site is for adults only.
Of course, some children will lie, and chose to view the site anyway. On the computer, however, there are more options. When we add new images, it takes a little while for them to be processed and transmitted to various servers. If a recently added image is not available, it should be available within a few hours at the most, so just try again later. If it is still not available, there is probably a problem, so please let us know.
