From Geocites Terms of Service

When I try to go to my page, I see a "Page Not Available" message. What does this mean?
If you have received the "Page Not Available" page when viewing your site, you may need to create an index page. For more information on creating an index page, please see this help page.
If you've already created an index page, and you're still receiving the "Page Not Available" page, your page may have been suspended for violation of our Terms of Service, if any of the following statements are true:
Pulling files from your GeoCities account to a location outside of Yahoo! GeoCities, such as auction sites, message boards, and other web sites.
You might try to put the pictures on a webpage, label it index.htm and provide a link to your site's homepage. If you make more pictures, make a page called something like mypictures2.htm and put them on it. Then, offer a link to that page.
Geocities frowns on simply providing storage. They want you to build a website.
