I am looking to add a image gallery to a html page where our service guys can log in and add photos of completed work.

Looking for suggestion on program / 3rd party software where our less than computer friendly staff can add photos of completed work.

Site is built in html and really dont want to to upgrade to Wordpress

Need something nice and has categories. Please advise suggestion or where to look.

Thanks

How are they going to take pics? Transfer to computer? Relevant for a variety of reasons.

How are you going to examine the pics? Who will have access to examine? What sort of ancillary info will be needed with each pic? How do you expect to control access to the upload facility?
