I cannot send photo attachments since yahoo changed to flikr. all I get is "the host yahoo cannot be found" please can someone help get me going again. was it because I was too late in trying to transfer?

well, Yahoo have been advising people who used their Yahoo Photos site to transfer to Flickr before 8 Oct. After this date Yahoo Photos is not available anymore.

If you are using mail to send attachments, then you can send photos, but you can't access the Yahoo Photos or your albums if you haven't transfered them to Flickr already

I had a few e-mails from Yahoo advising me to do that.

When you get delay in uploading pictures, your session gets timed out. But I think you can do it successfully with a good internet connection speed.
