There is no way i am able to default an image when the user doesnt upload a profile photo. Also, i am not able to chang the default that appears in the Softr List Details view, 3 column. I am taking input from a form where there is an option to upload a pic but its non mandatory.
This has been taken up with the support team but haven’t been resolved yet.
You can use a default image if the user leaves the field empty.
When configuring your form, enter a hidden field, map it to an attachment or URL field in airtable and enter the URL for the image that you want to set as default.
Then work a basic logic in airtable to overwrite the attachment field if the user enters a value for the image field on your form.
