Can I post a photo upon request?

Question

Startups

Good afternoon. I have an information site with a banner ad about interior design.
designers offer to publish their design project on my website, while they send me information about the object and a photo or 3d visualization.
Can I use their photos only upon request?
if not, what contract or permission should I enter into with them?

Answer 1

Write in the user agreement that the placement of content is allowed upon written request, including electronic correspondence.
Report this to the designers, and, in writing (mail correspondence), record the fact of permission.
But, in addition to this, it is better, in addition, to familiarize yourself with the nuances of copyright .

Answer 2

Resolution is cool.
But the service will crash.
Enough offer.
