I've had the same experience on occasion and I don't think there is a "general" solution involving e-mail. There are just too many e-mail programs and e-mail systems out there, all with varying standards, settings, defaults, and built-in capabilities. In addition, there are a large number of graphics formats and graphics software, many of which are more-or-less specific to various computing platforms. If you know who you are sending the files too, ask them what platform they are using (Mac, wintel, UNIX), what software they intend to use to view the images, what graphics formats the software can (supposedly) read, what e-mail program they are using, and what file transfer formats (e.g., binhex, zip, uucode) the e-mail software (supposedly) can handle. Then you can format your images accordingly. Obviously, this is not the generalized solution you are probably looking for. The two (more general) alternatives that immediately come to mind are ftp and the web. I've found that placing your images in a series of standard formats in a public-access ftp site works pretty well for most people. This doesn't get rid of all graphics format/reader problems, but it does allow you to place documentation of the formats (as a readme file) with the images, thereby largely shifting the burden of matching the format from you to the user. Also, I've found that ftp programs are much more standardized than e-mail programs. By far the most general solution to the problem of graphics transfer that I've come across, however, is via the www. If your images can be formatted into one of the standard web graphics formats (gif, jpeg) you can easily load the files up to a web site in the same way you would upload the image to an ftp site. Then, anyone with web access can find, view, and download the image from that site to their own computers. This will work for any size image (subject to the viewer's patience) and is relatively foolproof. Thousands (if not millions) of people "copy" images off web sites using this method every day. As an example of this method of image transfer try accessing and downloading the ammonite image from this address... http://www.nhm.ac.uk/paleonet/PalaeoVision/Ammonite2.Gif Hope this helps.
