If I select 'Default' as the layout the thumbnail has a number at 'Header 2 Right' which is Attribute = Index. I'm assuming this is the number given to the file of the Total file count, so if there is 100 files in the Database the files will be numbered 1 to 100.
If I select 'Thumbs small with icons' as the layout the thumbnail has a number at 'Header 1 Right' which is Attribute = OID (Decimal)
I'm not sure what this number represents. Is it something to do with the Total Count of files that have actually been in the database.
Each file in the database has its own unique one of a kind OID, it's a way IMatch can keep track of each file regardless of what its name or location is. The only time I've ever had a use for it is in scripts.
The index is the index of the file in the current file window, starting at 1.
The oid is the unique internal id of the file. I use that for testing and it's useful for scripts and Apps. Seems I have used it in one of the default layouts. I will swap this with index for the next release. You can do so too if the oid irritates you.
Thanks guys
