I tried to attach a picture. Got the message that the URL was not of one of the 4 acceptable types, however, the original picture was a ".jpg". I checked.
The URL I attached was of the picture in Picasa.
I supplied the password for my files in Picasa.

Help. What's wrong.
I also sent a message to the forum admin, but it was rejected - can't see why.

Thanks. Are there explicit instructions I should have been able to find somewhere on the forum?
