How do I send a high resolution photo from Picasa? (Using full resolution)

You can send a photo in its full resolution using Picasa. You must set Picasa’s email options to send the photo in its original size, and you can only send one photo at a time.

1. Open Picasa.
2. Click “Tools” > “Options” > “Email.”
3. Under “When sending single pictures, resize to:”, select the “Original Size” option.
4. Click “OK.”

Once this option is selected, any single photo you send will be the complete photo file. At the present time it is not possible to send multiple photos in their original sizes.
