Secure way to solicit image uploads?

Hey,

I am working on a project where I need to solicit images from the public for a dataset. I am looking for a secure way for them to upload them, keeping in mind I have to avoid any hidden nasties in the file at my end.

I have looked at Google forms but users need a Google account to submit images in the form. I’m not sure about directly into a shared Google sheet, this might be the same?

I tried using an Airtable form linked to base. Was looking good but it’s a pain because I can’t hide the first row of the form when they submit second image.

Example:
Name
Email
Image Name
Attachment

On second image they are required to complete first two lines again, which will annoy people.

So my long winded question is, what would you use to accept images?
