Any ideas on how to change the display order of photos?

I have users upload multiple photos and I am looking for a way for the user to choose what order the photos are displayed in.

I currently have a field in the Photo object named Photo Order, with a dropdown numbered from 1 to 20. Then a list that displays the photos in photo order. 

It sort of works but users can select the same number for a different photo. If they upload 5 photos and used the Photo Order #1 for all of them, then it's a lucky dip which order they will be displayed in.

Any ideas on a better way of achieving this?

Hello Robert,

 

As per me it's look like possible using jQuery. 

Like when user click on Dropdown then you need to check all other images Order number if match with any then disable that option.

 

if you required any help then plz mail me

That would be perfect. Any idea on how to disable that option for the other images?

Hello Robert,

 

If user select Order 1 for any image, then you can disabled this option for all other images.
