Sonia - By random strings do you mean in the address bar? If that is correct they are either a session ID value or a GUID value returned from the Yahoo database that points to your newly added account.

If you look closer to those imgaes implemented in a few major websites, the pictures are presented by CAPTCHA. And those images have got their names from there. (they are called CAPTCHA images)

this project can be found at captcha.net, and for Asp .Net you can see this link

You will need to signup for a key with them, so that you can verify the similarity with what the user typed and the image
