Image alt description writing for photography website

We are currently rebuilding a photography website and have a huge volume of images that need descriptions. It would be a combination of ChatGPT and Squarespace internal AI descriptors to combine the output. We have a fast system for doing this but need someone quick and accurate to work through this project. Images need to be copied into ChatGPT with a prompt to generate suitable descriptions which need to be checked then copied into the website.
