I'm not really familiar with Picasa - is it a pic sight? I'll google it and find out a minute. brb..........
Ok, it is a pic sight, just as I thought. I really have no idea abt sharing pics from there and posting them on DG. I'd go to cameras or computers forum and ask some of the folks there. GW or (sorry, just went blank, the member from Quebec) are very helpful with camera and computer stuff.
If you are just quoting text from a sight, you would do it the same way as quoting someone in DG. An example: Wikipedia entry: [ quote] 1997 - Diana, Princess of Wales, dies in a car crash in Paris. [/quote] becomes
