Awesome! In your case, you can either iterate over the dataverse rows or iterate over the photos.
1. Iterate over all of the images in the OneDrive folder.
2. Get the name of the image (2100. png), and extract the SKU number.
3. List Rows action in Dataverse with row count = 1 and filter rows "sku_column eq varImageDisplayName"
4. Use the Upload a file action, select the record ID, and upload the image contents to the record.
