WEB database development

We have a website and we need to add the following service: On one of our webpages we would like to have have a collection of clients with small photo/picture of each client and short information about the client. Then by clicking on the photo that should redirect to a personal page with a large photo and more complete information (say 10-12 items) for each client. To manage this page we would like to have an interface (accessible only to the WEBsite administrator) on which the administrator would be able to enter the data about the client in the dedicated fields (textboxes), then upload the picture and finally press on a button so that the new client is automatically added to the page with the small pictures and to the personal page.
