'How do I easily shrink photos and mail as attachments using Thunderbird'
I have been asked this question a number of times locally and I don't see a mention in the forum.
So here is a tip for newbees!
First check Picasa is updated to version 3.
Then in Control Center, open KDE Components, Component Chooser, Email Client.
Select> Use a different email client, and set preferred email client as Mozilla-Thunderbird.
To send photos, open Picasa3, highlight desired photos, click on the email icon (send photos in the photo tray by email)
Select use native Linux Client, and a Compose New message will appear in Thunderbird with shrunken photo(s) pre-attached.
A test 3MB photo @ 3027 X 2304 JPEG was auto-sized to a happy-snap 54KB @ 480 X 360 pixels
The compression factor can be set in Picasa, Tools, Options, Emails...
