Getting pictures described

So I make funny and poetic Twitter bots and lately I have been adding pictures to the tweets. I would like to have some way of getting basic descriptions for the pictures, so I have at least some confidence that the pictures are of what I think they are. The only thing is, for technical reasons due to how my bots work, I have been using pictures I find on twitter. I have no idea how I would run such pictures through any of the IOS apps that describe pictures, because I do not believe you can import from Twitter with these apps. Also, when I tweet the pictures, I am just taking a special link that Twitter creates for every uploaded picture, I'm never doing anything with the picture files themselves. In other words, I search for pictures on twitter, copy the special link from a tweet that seems promising, and then paste that link in my bot to be added to future tweets. I'm not sure how I would save each of these pictures to my phone and then run them through an app, and I would really really rather not have to do such a tedious process.

A while ago I remember hearing about a twitter bot that you could tweet pictures at and it would try and describe the pictures with AI. Does anyone know of a twitter account like this? Does anyone know of a website that I could upload a picture to from the desktop and get a description?

I would love to hear any suggestions for my problem. By the way, if anyone is interested my Twitter bot is @QuotingAI , you can find it at here. https://twitter.com/QuotingAI
