You can create a form on your interface with an attachment field, and then people can drag-and-drop multiple images in there at once.
Then, for separating them out into multiple records, you would need to create an automation that would loop through the attachment field and create a new record for each attachment.
To do this most effectively, your form submissions should probably feed into a DIFFERENT table that would just be used as the "temporary holding tank" for the form submissions. Then, the files/records would live permanently in your main table.
