We reference all graphics into our documents. Currently we have a couple of thousand graphics stored centrally in the same folder location. While it can be a bit cumbersome to maintain that many graphics in the same folder, it ends up helping us in the long run because if a graphic is updated, it gets updated in *all* locations where it is used. Previously we had project-specific graphic folders, and we found that the same graphic might be updated for one manual, but not for another.
We avoid naming files by document name or figure number because of the reasons Bob Kern mentioned (if you insert one in the middle, what happens to the numbering?). Also, most graphics are used in multiple locations, such as in the User Guide and in the Maintenance Manuals, so the fig. numbering really didn't apply for all uses. Instead, we set up a naming scheme that incorporates the product/s the graphic is used for and a pre-defined set of procedural/descriptive words. It took some time on the front end for our graphics team to set this up, but it seems to be working pretty well for the most part. Also, if links are broken, there is only one folder to point to for updating the path. -Carla cmartinek at zebra.com - CONFIDENTIAL- This email and any files transmitted with it are confidential, and may also be legally privileged.
