Startup message image

I am trying to make my own config of Gnu Emacs. I want to do a custom startup message, where I put an image and a caption under it, I found how to get the message, but not the image? How can I add an image to the emacs startup message? Thank you

Look at the `defcustom`s provided by `startup.el`, the library Emacs uses during startup. In particular, `fancy-splash-image` and `fancy-startup-text` are two customizable options you should explore.

this may be overkill but you can use dashboard-mode
