adjusting size of photo prior to emailing it

Preview is an application that Apple provides on all it's systems as a general image viewer, PDF reader, etc.

I believe the Preview icon (picture of a couple of photos and a magnifier) is on your Dock by default. Get to know it, it's very handy.

If using Apple's MAIL app to send email, you can copy/paste the image to the email. Once pasted, you will have a drop-down menu for re-sizing. You can choose SMall, Medium, or Actual Size.

This would not work if sending the file as an attachment.

To resize an attachment, use Preview to re-size if that's the case (as mentioned above).

Preview is an Apple app (separate from iPhoto). Open the image with Preview. Choose 'Adjust Size' from the Tools menu at the top. You can resize by percent or pixels.

To send pic via Comcast email:

Per RatVega: use Preview to change size of photo

Preview > Tools > Adjust size

Change size by changing height & width > check Resulting Size box

at bottom of box. Adjust numbers to make file the size you want.

Save As...Name & put file where it's easy to find, such as on Desktop

Go to Comcast mail

Click New > Set up new email.

Click Attach at top of email window > Attach File window opens

Click on Choose File > Finder window opens

Click on the pic file you set up in Preview > Click Choose button

This takes you back to the Comcast Attach File window.

Check that your files there, to the right of the Choose File button

Click Attach at bottom of window

Wait a couple seconds > email will open with file attached.

This isn't quite as tedious as it looks. It does get the pic sized & in Comcast.

Good luck.

Thank you. This has been most helpful. I just sent an email with two humungous pictures attached and I knew it was time to learn how to reduce their size. I didn't even know Preview existed until I searched the Community. I found your answer most helpful and have been having a play. Obviously a lot more research to be done! Thanks for posting your reply.

Open it in Preview and use the cropping and re-sizing tools there.
