Uploading Pictures to Picasa Web

This can be done two ways:
1.Use the web application.
2.Use the Picasa desktop utility.
THrough Windows,I have used both the ways with ease,especially thesecond one.Only when I got constrained to use Ubuntu that I realised the following issue:
Amazingly,the web application let us browse and select one pictures at a time...for 5 pics ,after which we need to click on upload button.In Windows,after clicking on Browse,I could select all the pics in one go..and hit Upload...and it will upload all the pics...thus I felt irritated with this limitation.
So I installed teh Linux version of Picasa ....disappointment again...as it does not hsve option to export pics to picasa web...the very reason i instaaled it...googled and it confirmed the fact that google has looked at picasa only from Windows perspective...that is sad.
Soultion:FSPOT.....select the pics,File->Export->Picasa Web ...it will prompt for the Picasa web user id and password....and that's it

But then ,one fine day...it suddenly began to ask for some default keyring password,which I had never set.After a lot of googling,I got something.In the Administration link ,click on Keyrings....view Keyrings...try to delete the default keyring..I did ..and it worked.
