Mistakes People Make with E-mail Photographs

You have probably received huge photos that took hours to download or pictures so big you could only see a corner of the image. Here's how to avoid doing these things.

Photographs That Are Too Tall and Too Wide

If a picture is too big, it cannot be viewed properly. The recipient will not be able to see the entire picture at one time because the image will go off the screen. The person will have to scroll up and down and side to side and will only see part of the image at one time.

You should match the image size with the resolution of the recipient's monitor. The best all-around resolution for e-mail is a fairly small size such as 320×240 or 480×360. Any e-mail program should be able to view this size.

While you can probably get away with a larger size such as 640×480, remember that the e-mail program itself takes up a lot of space on the screen, leaving very little room for a full picture.

If you know the person you are e-mailing has a high monitor resolution, then by all means send a larger picture. Nevertheless, you will need to keep the picture considerably smaller than the full size of the recipient's monitor.

Viewing large photos can be confusing because many viewing programs automatically adjust for a size that is too large. Generally speaking, pictures that are e-mailed in the body of the message will not view properly if they are too large. However, attached files can be downloaded and then viewed in a separate program that can resize the image for viewing.

Photographic Files That Are Too Large

Very large files can take a long time to download. In addition, some e-mail services may not send or receive very large picture files. It is a good idea to keep the size below 150KB and an even better idea to keep a picture below 50KB. Use the JPEG compression feature to compress the file to the right size.

JPEG and GIF files are the main still-image file formats. These can be read in an e-mail program and in a Web browser. A few programs might be able to read TIFF and BMP files, but don't count on it.
