Building a Website

I am very,very new to website design so please bear with me. I was told that DNN would be the best way but I am not convinced. I basically need my website users to be able to save information from their photos on my website. I prefer not to save the photographs themselves just the data from each. This information will be saved and available to develop charts from. Here is what I’m thinking:

? User has logged into my website.
? User needs to upload information from new images into website.
? User selects “browse” button
? User opens folder of new images.
? User selects all of the images
? The software opens up a viewer allowing the user to view the first image from folder.
? The drop down menu is opened for the user to select what is in each image. This is probably something I will need to put in.
? User selects what is in each image from the drop down menu then click “NEXT”
? The software reads and determines whether the date & time of that image is prior to any previous image saved by this user.
o If image is prior to any previous image saved then the data is deleted.
o If image is post any previous image saved then the data is saved including information keyed in from the drop down menu.
? The saved data is available to use to develop charts from. The charts will show what was in the photo as well as when the photo occurred.

I’m just wondering whether WordPress has this type of capability or whether another platform would be more suitable for my needs. Any help would be greatly appreciated.
