Using img2img function, how do I exclude the filename from the resultant prompt?

[createchange]

I have randomly named files, and it wouldn't be economical for me to go through and name them.

Is there a means by which I can generate a shortcode that does not inject the file name as a parameter in the prompt?

I realize now that I didn't put in the effort to understand the tool and it's extendability.
