A family of Microsoft relational database management systems designed for ease of use.
In all honesty we have never been made aware of project requirements, statement of purpose, scope, number of users, security, how the application needs to be updated and distributed, how data changes will be handled, etc. I have asked but never been answered. How can we get you somewhere when we really have no idea of where you are going. It's like we are in the back seat of a car offering directions without a clear understanding of our final destination. We know full well how to drive and shift and obey traffic laws and navigate but the drive often makes the same mistakes, doesn't seem to hear, plays the radio too loud and doesn't respond. Apparently the driver knows how to drive a tractor in a field but we are in a nearly self-driving car.
I have also suggested several times that based on your need for distributing this application across many locations with limited resources and who knows what age of computer, you should consider a web based application. This would allow for instant updates to all users worldwide, You could restrict access if needed. There would be absolutely no cost to any end user unless you wanted to charge a subscription. Images would be available to all users as long as they had a computer, tablet, or phone connected to the internet. No installing anything anywhere.
If you want to continue down the Access path, please consider creating one new thread with the information I suggested in the first sentence above. Also provide what you currently have which I believe is thousands of images.
