Sending pictures to email lists

The photo files coming out of your camera are good for printing (very high resolution)  but are horrible (for many reasons) to send to large numbers of people on email lists.


Tips and Guidelines for Photos

  • Almost any image program will allow you to shrink the file down. You should be able to get a picture file down around 50 KB and have it look good on the computer screen. Experiment with the settings and then check the new file size.
  • You should be able to set the picture resolution to 72 dpi (dots per inch) and the dimnsion of the longes side of the picture should be no larger than 640 pixels.
  • Make sure you use "Save As" so that you do not shrink the original picture.
  • A New York Times' tech Q&A has some tips on how to shrink photos.


Platform specific instructions


If you're a Linux user, you already know how to do this ;-) Seriously, some options include the GIMP (GPL), commercial offerings, e.g., Lightzone (free) and RAW photo processing -- Raw Therapee (GPL). Here's a nice tutorial.


iPhoto -- select the photo and click the e-mail icon at the bottom of the window; a box will pop up asking if you'd like to shrink the image for e-mailing.

Apple mail -- in a new message window, click the "Attach" button to add a photo file, or drag a photo file icon (from the Finder) to the message window. At the bottom of the message window, it shows how large the messgae will be. You can adjust the size using the "Image Size" menu at the lower right side of the message window.

If you spend a lot of time working with photos, want a powerful graphics program, but can't afford to buy Photoshop, check out Graphic Converter.


(Please note: The DBC Race Team webmaster does not have Windows to test the following instructions. If you have a better solution or suggestions, please let him know.)

  • Right click on an image file and select "edit"
  • This will open the file in the MS Paint program
  • "Image" menu -> select "Stretch/Skew"
  • Choose (equal) horizontal & vertical percents (try at least 50%)
  • "File" menu -> select "Save as"
  • Now, locate the newly saved file and check the size (right click and choose "Properties"). If the file size is < 200 KB, you're set. If not, retrace the above steps and try larger percentages.
  • There are many free or inexpensive image editing programs. You might start with Microsoft's "Image Resizer," available here, or try Portable GIMP (free) or Picasa photo-management program (free).
  • There are also some online image editors, such as JPEG-wizard and Phixz.
