Adam,

 

We sell ads.  Ads include up to two photos, an extra charge applies for each additional photo.  Additional photos can be added at any time. 

 

Sometimes, someone will upload a photo, then change their mind and remove it.  Sometimes someone will upload several photos, then change their mind and remove one or more.  I need to know exactly how many, and which photos the user wants.   So I need to know when a photo is removed, and which one.  It would be easiest to removed the unwanted photos, but knowing the file names would also work, an the files are manually resized and moved over anyway.
