You're in luck. You can use the Object > Captions > Caption Setup to pick Name as the metadata. Then when you place the file turn on Import Options and check Create Static Captions.
You also can create dynamic captions which pull other metadata from the images but it doesn't sound like that's what you need.
Also you can read more about Captions in InDesign Help.
There is also a script that will batch all images in a selected folder into a grid and place the filenames as captions underneath. You should find it in your scripts window – ImageCatalog.jsx
That is excellent! Thank you so much. I am going to try this first thing tomorrow then I'll report back. I'll check the ID caption info you suggested too. I'm assuming I can batch many images at once in my ID frames and the little text boxes will follow along? And I can still move the image/caption sets around in my document like normal text and image? Thanks again - most appreciated.
thank you - I will try this too.
