When creating your graphics on the Mac, you should definitely have the software add the extension, whether it be .tif or .jpg, to the file name. Windows machines do look for this extension to determine what type of file it is. If the software won't give you this appending option (usually there is a check box for this option when you are at the step of saving the file), then add it manually by renaming the file with the extension.
The problem of the file type being "unknown" is probably a result of two things. 1. Attempting to open by double-clicking on the file and the computer not knowing the file type; and/or 2. The computer not knowing which program you wish to open a graphics file with the extensions .jpg and .tif. Any number of programs can recognize and open such files (Photoshop, Painter, Paintshop Pro, etc.). Internet browsers are the main users of .gif and .jpg files so this is why the browser opens such files by default when you double-click the file. Somewhere in Windows you can designate which program you want to open such files when double-clicked. Or you can avoid this whole mess by first opening the program in which you wish to view the image and open the file from within this program. The email attachments issue is another ballgame entirely. It is probably a function of the email application. Email programs have to process an image in order to send it. They compress the image and attach it to the text file of the message. There are several formats for this. Have the person who is emailing the image check their email program's Preferences and click on the "Attachments" section. There are options like Encode for: Any Computer, Mac Format, Windows and some others. Have the sender choose "Any Computer" to be safest. Hope this helps. -- Barry Madore Technology & Web Development Specialist MAP for Nonprofits Direct: 651/632-7235 MAP: 651/647-1216 email: [EMAIL PROTECTED] MAP web: http://www.mapnp.org ------------------ Reminder to each recipient: To change your list account preferences, go to http://email.sparklist.com/scripts/lyris.pl?enter=support and enter the email address you used to subscribe to the ebase support list:: [email protected] To unsubscribe send a blank email to [EMAIL PROTECTED] --------------------------------------------------------------------- ebase - Relationship Management for Nonprofits, http://www.ebase.org ---------------------------------------------------------------------
