My customer, an agency which rents out apartments on behalf of landlords, has a server on which they store all their files. These letters are generated by their property management software, and are written to their landlords, tenants &c. Obviously they have to keep a big archive of copies of all the letters they've written in the past. The letters are stored in .doc format, but when they're originated I think they're actually just printed out and posted. Storing the signature in the .doc is, I think, just a convenience to save the boss (or other members of staff) having to physically scribble a signature at the bottom of each letter. I'm guessing the office might manage c 100 properties, and I imagine that they may generate some thousands of letters per year. So a 1meg image in a letter might well start to consume gigs of disk space. "Gigs of disk space" is only a little bit of a problem because when this server was manufactured, 4 years ago, decent RAID meant horrendously expensive SCSI disks (it is still under support contract for another year) and because I haven't got around to migrating them away from an offsite-backup provider who is somewhat overpriced. Hope this clarifies, Stroller. PS: a couple of great suggestions have been made this afternoon. I'm going to watch some of the fruits my labours - my labours involving get_iplayer earlier today - and will try these suggestions later. Many thanks!
