I'm replacing an Extensis Portfolio image database on the web with one embedded in an e-commerce system and I'm cleaning up the old database in preparation. One of the preps I'm doing on the old files is to rename them with meaningful English names, for which I'm writing an AppleScript. My question is how long can I or should I go with a filename phrase before I start breaking web pages or image links? Remember, these are file names not page titles. Obviously, the more information the better if no harm is done. Should I target a filename length of say 40-50 characters? Would 70 chars be too long? Any insights appreciated.
