The FAQ's are quite detailed, as Ellis states.

You do need to understand some fundamentals, like image size and pixel count and image compression.

I just a google search for "jpg file resize" and got many hits.

One was a web site which will convert. See URL link. This was a very easy site to use. A few seconds to get a resized file and it shows the file size before saving.

For people with Windows XP, this is another option. More mouse clicks, but useful.

1

Locate the JPEG file you wish to resize. Select it and right-click.
2

Find the "Send To" tab, and locate "Mail Recipient." Click on this.
3

A new window titled, "Send Pictures via E-Mail" will pop up. The two options listed are "Make my Pictures Smaller," or "Keep the Original Sizes." Select "Make my Pictures Smaller" and hit "OK." NOTE: For more detailed compression options, click the "Show More Options" tab in the bottom left-hand corner of the window. You can choose between three possible reduction rates. Hit "OK" when finished.
4

An e-mail message will pop up with your resized JPEG as an attachment. Send it to the recipient of your choice.
5

If you want to save a copy of your resized JPEG file, go to the "File" tab in the top left corner of the e-mail message window, and select "Save Attachments." Choose the location to save the new file and hit "Save."
