Amazing value vs Images

I own a software the generates marketing images, and I've automated my tool to create these images for leads and I want to leverage them as the value proposition for my cold outbound. They are very heavily tailored to the lead and would genuinely cost them a small amount to purchase themselves.

I can generate these images and embed them in the email automatically, but I'm concerned about all the negative posts I've read about including images in the first email. I'm trying to figure out whether or not the value that these images would add would outweigh any negatives that you would see from including an image in an email.

Or, would I be better off sending an initial message, "I've created these images for you. Let me know if you'd like me to see them?.

Finally, if I am to include the images, is embedding them in the HTML the best way to do so?
