I am a rather late convert from PC to Mac, so I keep discovering something new (maybe not so new for my geeky colleagues ☺) every day. Today I found something that I felt it would be a sin not to share.
For a long time, I have been figuring out a good way to send photos home to family and friends in China. I may be too fancy, but I tried Web Shots and flickr to share photos with them, but for one reason or another, these sites were either blocked in China or require some sort of authentication that may be challenging for some as the instructions are in English. And most of them don’t use Facebook either. So to make lives either, I have gone back to the old-fashioned way to send photos: by attaching them to emails.
However, I found some photos are too large to send by email (some as large as 2M, because I forgot to configure my camera or chose not to), so emailing such photos would annoy people tremendously. If you just want to share some photos for people to view on the computer, you really don’t need to send a 2 MB photo. Yet you may select such resolution any way because you want to use it for some other purposes that require high quality of image. So how to resize and re-purpose these high-quality images? I used to go to some web sites, which offer resizing services, but this would require you to upload photos, resize, and then download, etc. It’s painful.
I discovered that with iPhoto on Mac, this problem can be solved fairly easily. For those who use Mac email, you will notice that you can select the size of attached photos when you attach them. Mac email will then resize it for you automatically. If you don’t use the Mac email, here are some simple steps in resizing your photos before attaching them to your email.
Here are some simple steps:
1. Launch iPhoto;
2. Find the Photo you want to resize. You can find them from “events”, if you have organized your imports into events, or you can search for them from your “last import” or “last 12 months” options;
3. Select the photos (Holding down “shift” to select whole rows or columns, or “command” to select multiple photos one after another)
4. Click on “file”
5. Click on “export”;
6. Select “file export”;
7. Choose your configuration here, for instance you could select “JPEG” for file “kind”, and “medium” for “quality”;
8. Here is the important part: for file size, select “medium”, which would drastically reduce your file size;
9. For file name, choose one of the options. I usually select “sequential”, and give it a prefix, such as “graduation” for prefix. Your photos will then be named graduation01, graduation 02, etc.
10. Click on “export”;
11. Select the place to export the new files to, or simply make a new folder for this new group of photos. Then click on “OK” to finish.
I found, much to my surprise, that the size was reduced from something like 2MB to 100k. I then emailed these photos to myself to see if the quality was compromised as much. To my surprise, the quality of photos was very identical. Yet what a world a difference there is, between 10 MB and 600 KB of attachments!



Thank you so much for the help. What a relief. I’ve been struggling with this system all day. I’m annoyed that the procedure you suggest is not spelled out anywhere in Mac help or in iPhoto’s user guide. I guess we’re expected to be born with all of the essentials implanted on a chip. You’re very kind to share it.

Mr. Simmons, I am glad you find that helpful. Thanks for the feedback.
Thank you so much for the easy to follow instructions. I have been grappling with this problem for quite sometime as I have a blog Adventures in Africa at eveavila.blogspot.com. I am glad that you are also using Mac.
Thank you!!!!!!!!!
You are very welcome.
Just got my first MacBook Pro. New to the Mac wold, I was looking to reduce file size of my photos. This is just perfect !
I knew a fantastic trick under Windows to achieve this. And this is very much like it. Thanks a bunch!
Thanks for the amazing help! I have to send photos through email for work and someone told me that the company “process” was to give all the pics we wanted to email to our graphics person and have her resize them in Photoshop for us. Every time. So not efficient. I’m glad I found your advice!
THANK YOU SO MUCH!!! I tried inserting a photo into the body of an email & it was so huge. I wonder why you can’t resize the photo in the email as I could with my PC? Anyhow you helped me solve my problem. Thank you SO MUCH.
Many thanks for the guide to reducing photo size for e-mail with Mac. I was baffled, couldn’t find a way myself, till I read your step-by-step guide. I am new to Mac and I find so much about it to like. But Apple appears to assume that its customers are such sophisticated connoisseurs of the system that they don’t need help like lowly PC people might. Me, I’m not too proud to beg! Thanks again.
