Making an NFT batch with my own Art

I am sure I found the right place to ask this question, but after reading the last hour and a half of posts, I’m way out of my league. But here it goes:

I have generated in excel a 823,543 unique outcomes with 7 different images, which each have 7 different variations.

I would like to now take those 7 different images and variations and have a machine build 7,777 images that would be randomly selected from the total 823,543 outcomes.

Can this be done with TensorFlow?
