DI reader Sukhwant Sandhu is looking procedure to help him shift all his photographs from Yahoo! Photos to his Google Picasa Web Albums account. So here's a step by step tutorial followed by a video tutorial at the end:
Step 1: Install the free Yahoo! PhotoMail plugin on IE browser by clicking the Get Started button on this page.
Step 2: Compose a new email message inside Yahoo! Mail and you will see a button called "Insert Photos" next to the "Attach Files" button.
Step 3: Click the Insert Photo button, choose the Yahoo! Photos from the dialog that appears and drag-n-drop Yahoo! Photo albums to the message. Yahoo! will automatically attach all pictures from the album to your message. Click OK.
Either send that email to your Gmail account and download all the Yahoo! Photos as a Zip file to your hard drive or address that to your secret Flickr photo address to upload on Flickr via email.
Tip: The Yahoo! PhotoMail plugin is currently available only for IE. The attachment size limit is 10 MB so if you have hundreds of photographs in your Yahoo! Photos albums, send them to Flickr or GMail using multiple emails.
