Welcome to the community, @Tricia_Hagey! :grinning_face_with_big_eyes: Unfortunately Airtable can’t access your local files without manual intervention. In other words, the only way I know of to do this is to browse for the files one-by-one and add them to the appropriate records.
There might be a way to enlist the help of some third-party services; e.g. put all of your images into a Dropbox folder, then use either Zapier or Integromat to parse that folder, find the matching Airtable record for each image, and attach the images to their matching records. I’ve never done something like this, but it’s probably doable.
