For such inquiries, include details about your computer, operating system, software used, and a complete description of the problem.

Working with Graphics
Format for saving graphics files
GIF or JPEG Format. To be displayed by a WWW browser, a graphic must be in GIF or JPEG format. This format is useable cross-platform, i.e., by Macs and PCs. You must work in RGB color mode to be able to save to either format. GIFs then need to be saved to Indexed mode. Generally, drawings should be saved as GIFs. Photographs should be saved as JPEGs, to preserve their clarity. If your graphics software cannot save to GIF or JPEG format, ou can get a shareware converter to do so via the Internet.

File size. To keep the file size small, make the image no larger than 4 inches by 4 inches. Make the resolution 72 d.p.i. (the maximum any monitor can resolve).

Alternate format. Most Macintosh graphics and scanner software and can save in PICT format. If you don't know, single click on the file and choose Get Info to check the format. Windows graphics and scanner software can save in PCX or BMP. If you don't know the format, single click on the file and choose Properties. If you are unable to convert to JPEG or GIF format (see below) please use the above formats to save your files.

Compress. If you can, compress graphic files larger than 200K before attaching to email; if you can't, just attach and send the graphic as is.

File name. Include your group name and the observation due date in the graphic name, like this: brooks1019 or ridgeview1005.

Converting Graphics to GIF or JPEG
If your graphics software does not save to GIF or JPEG format, shareware converters are available online for download.
Macintosh GIF Converter: shareware at CNet; Search for Gif Converter.

Windows LView Pro: graphics viewer and converter available at CNet, and search for zip or compression.

Compression shareware
If you cannot convert your graphic to JPEG or GIF format, before emailing, you can compress its size to speed transmission and to protect the file's integrity.
For Macintosh: You need: 1) Stuffit Expander (decompresses): You need StuffIt Expander to decompress most files you download from the Internet. If you do not have StuffIt Expander, the easiest thing to do is to ask a friend who has a copy to give it to you. Otherwise, go to the Aladdin Systems site and read their instructions.
2) DropStuff with Expander Enhancer (compresses and beefs up Stuffit Expander) is available from CNet.

For Windows: WinZip is available at PC Magazine's site. It's is a self-extracting file, i.e., it decompresses and installs itself.
