The image file to be emailed should be a fairly small file. A huge file can be dreadfully slow, both to send and receive. Printing does need larger files, but a video image should not be larger than the recipients screen, perhaps 800x600 or 1024x768 pixels. Don't scan for email at 300 dpi (way too huge for screen viewing). Scan at perhaps 100 dpi for email. Images scanned at 75 to 100 dpi will appear (in the rough ballpark of) near original size on most common screens.

Scanning a 6x4 inch photo at 100 dpi creates an image size of 600x400 pixels, generally large enough for email purposes (for screen viewing). This 6x4 inch 100 dpi 600x400 pixel image consumes 720K bytes in memory. Or scanning 6x4 inches at 75 dpi gives 450x300 pixels and about half the file size of 100 dpi.

Save the photo image as a JPG file for email. JPG compression squeezes the data to be a very small file, which is fast for modems. It is usually around 1/10 the file size of other image file formats. There are quality losses due to this extreme compression, but a moderately high JPG Quality factor setting gives a decent quality image (see page 134), and still reduces this 100 dpi 600x400 pixel 720KB image to a JPG file size of about 75KB. It takes perhaps 45 seconds for a 28.8K modem.

Or if you already have the image in some other file format, just open that image, and use menu FILE - SAVEAS to save a copy as JPG.
