Add way for custom GPT to upload photos to API

[bscholer]

I haven't been able to think of a way to have the custom GPT upload photos to the database. When you upload a photo to ChatGPT, it only has access to it in the code environment. In order to send it to the backend, it would need to convert the image to base 64, and then put it in the request, which isn't practical or possible really. Not sure what this will look like, but as of now, I don't see a way to pull this off, besdies uploading photos to an S3 bucket and getting them from there or something.
