By using gmail, you can easily upload pictures from Picasa to Flickr. New changes in Flickr allow you to upload the tags, picture title, and descriptions as well. Email from Picasa2 to Flickr: 1. Log into your Flickr account 2. Click the Upload-by-email link 3. Copy the email address listed on this page. You may also wish to set a global tag/tags to all pictures emailled to flickr. I use "email_flickr" or something similiar just for reference. 4. Load Picasa2 5. Within Picasa, click the Tools menu and then Options6. Selec the Email tab, select Use My Gmail Account, and set the size of picture you wish to send. 7. Click OK. 8. Select a picture or pictures to upload Note: All pictures uploaded at once will share the same tag, title, and descriptions; therefore, it is best to upload small, similiar groups of pictures this way. If you need to change information, just email another group. Even doing one picture at a time is still fairly efficent.9. Click the Email button at the bottom 10. Fill in your gmail information if it asks 11. In the to: line paste the email address that you obtained from flickr 12. In the subject line put what you want to title the picture 13. If you want to put tags you can also add tags on the subject line by placing them after the text tags:Example of subject line: Christmas Pictures tags: xmas tree Santa14. Clear the body of the email. If you want a detail description of the pictures, you replace the current text with whatever description you wish. 15. Click SendYou pictures will now be on flickr with the information that you set. Enjoy.
