another option is using sqlite for storing images. All data is in single file. (or files if you organize it that way) easier backup etc... you have some db benefits and retaining solid speed vs file system. Haven't used this, but seems as viable option to explore.
Thanks for the replies, and suggestion from Ognjen, Ben Chobot, John R Pierce, Tomás, and Karsten... I checked the links, and I decided, that I cannot decide :-) because I don't know, how large could be the infrastructure for this. If I store the images, and scanned docus in the database, a radically larger enviroment will be needed, than if I store only the link. My boss will decide, and I will implement anything, that he wants, I just wanted to collect some experience, that you have, and that you have provided form me, and many thanks for it :-)
