How did you get the images into the content management table? Did you import them? If so, did you enable auto-enter options during the import?
Check to see if the clumsily named CONTENT ID MATCH FIELD has a value for your images.
The first way I got the images in was with the bento file import.
The second way was exporting my bento file to excel, importing the file to filemaker and then drag and drop images to the "file container" in the contents details form.
I didn't know what to do with CONTENT ID MATCH FIELD, when viewing the field details it says "Indexed, Auto-enter Serial". I created all my own fields when importing.
What is CONTENT ID MATCH FIELD and did my import override something in it?
I created all my own fields when importing.
I sincerely doubt that you did anything of the kind. More likely would be that you created a brand new set of records during import.
I do not know for sure that this is the issue or not as this starter solution used a truly creative method of setting up the Thumbnails fields and layout and I haven't taken the time to explore every nuance of it.
But what I have suggested is to check the value in the CONTENT ID MATCH FIELD on each of your records. You can do this by entering layout mode on the Content Details layout and using the Field Tool or the Field Picker to add this field to the layout so that you can see the actual value in it. There should be a number in this field--a serial number that was auto-entered when each new record was created. What you don't want is for this field to be empty--which shouldn't happen for drag and dropping documents into the container field, but might happen if you used Import Records | Folder to import the files into the file..
I put that field onto my layout. It is empty, but I can enter data. I didn't use it when importing as I didn't need a serial number or any numbering of my data.
Could you please explain what that field is for.
