A lot of content and engagement question

If i have an account with 500 images and 1500 followers, should I delete images to increase the engagement rate? do they connect to each other some how?
Anyone can tell me more info about the coloration with the images vs followers?

I was thinking this too - to delete pics with no engagement. But I’m also thinking it makes sense to keep more posts since it’s more content and n my instance it’s more stock that’s available for sale. :thinking::thinking:
