Apple has published a tip on re-sizing photos in Mail “on the fly” which was picked up by TUAW (and others).

It points out that if you drag a full-sized photo into a new message window, you can then resize it using the drop-down menu in the bottom righthand corner to Large (1280×800 pixels), Medium (640×400) or Small (320×200) sizes:

Now, obviously, any Mail tip is a good one by definition and any resizing is better than none for your Sent Mail folder, your bandwidth and your recipient, but there is one thing that the tip doesn’t mention.

Mail sucks at resizing images.

A year ago, Rob Griffiths ran the tests and did the sums when the same tip was posted on macOSXHints. He discovered that Photoshop is between 61% and 73% more efficient at the same tasks. Even iPhoto itself does a better job.

Not everyone owns or likes sledge hammer apps like Photoshop, but if you do this a lot, you could consider utilities like Downsize or Scale to Mail, which will resize your images efficiently without the need to fire up the monster.

If you are reading this but for some perverse reason don’t use Mail, resized photos may still be within your grasp. If you use Claris Emailer, GyazMail, Mailsmith, Outlook Express, PowerMail or QuickMail Pro, Simon Jacquier’s iPhoto Mailer Patcher lets you hack iPhoto to set your email client as the recipient of resized photos.iphoto, mail.app, apple mail, images, photos, resizing, mailsmith, powermail, gyazmail, tips

MegaPixel Maven posts a tip on resizing photos in Mail.app using the “Image Size” drop box in the bottom right-hand corner of the Compose window.

As the author points out, you can use this function to reduce an image in the Compose window to Large (1280×800 pixels), Medium (640×400) or Small (320×200) sizes.

Three points:

• Mail does a really bad job of reducing the image. Rob Griffiths ran some tests on this when the tip was posed on macOSXHints last year. He discovered that Photoshop is between 61% and 73% more efficient at the same tasks. Even iPhoto itself does a better job.
• Another option is to use a utility like Downisze or Scale to Mail, which will resize your images efficiently without the need to fire up a monster like Photoshop.
• If you use Claris Emailer, GyazMail, Mailsmith, Outlook Express, PowerMail or QuickMail Pro, Simon Jacquier’s iPhoto Mailer Patcher lets you hack iPhoto to set your email client as the recipient of resized photos. Instructions can be found in an earlier Hawk Wings post.
