Set up your Airtable database with one text field which contains image URLs, and an attachment field. \n![Source example](https://i.imgur.com/IVIPQoo.png/<IMAGE-NAME>.png#full-width)\n\n2. In each Airtable node, add your Airtable credentials and connect to the base and table you want to modify.\n\n3. In the \"Get all records with an image URL\" node under \"Filter by Formula\", change the field name from \"Image Source URL\" to whatever your URL field name is.\n![Source example](https://i.imgur.com/32Z7DqX.png/<IMAGE-NAME>.png)\n\n4. In the third node \"Update attachment field with images\", update the expression with the correct field name for the URL field. \n![Source example](https://i.imgur.com/hUeZgxX.png/<IMAGE-NAME>.png)\n\n5. Click \"Execute Workflow\" and watch the magic happen!\n\n"
