If you want to play web with Guile, I suggest Artanis, which is a web framework for it. It's easier than using the lower web api.

Also tried to understand converting to bytes in the documentation but again... no luck. Always getting a 500 error. Yes, I have included (content-type . (image/jpg)) etc.

Please attache you complete code. But I guess what you need is get-bytevector-all which dwells on (rnrs).
Usually, open file only return a file port, you have to read the content then.
