I’m trying to build a very easy to use ai assisted tool for my dad.

What it would do : 

by the tap on a Shortcut from his iphone, it would ask him “how many”( = x)

Then, would take his last x last pictures he took, send them to zapier prompt an AI to describe them (and more), and would end by sending him an email with the response.

My issue is about sending multiple pictures. I was able to do it with 1, with the help of webhook and of this article : 

What should be the webhook parameters adapts to the number of files be uploaded (ranging from 1 to 10).

I had find a way, using dropbox, (then with a trigger on the dropbox), but the challenge is that I need all the pictures to be in the same prompt, as there is comparison and description of the whole.

I’m starting to look at the encode64, but the images are often more than 800 000 characters once encoded that way, it would use too many tokens.

I’m running low on alternatives or solutions! 

Any idea ?
