Struct ImageStore 

pub struct ImageStore {
    pub keep: fn(source: Source<'_>, editor: &Entity<Editor>, cx: &App) -> Option<String>,
    pub accepts: fn(path: &Path) -> bool,
}

Who owns the pictures a document points at.

Plain fn fields rather than a trait: a store needs state — which article is open, where the vault is — and in gpui that state lives in the app, not in a capture. So the store is handed &App and the editor doing the asking, and looks its answer up the same way everything else here does. Nothing to box, and Default means a field added later is not a break.

Fields

keep: fn(source: Source<'_>, editor: &Entity<Editor>, cx: &App) -> Option<String>

The URL to write down for source, and None for one the app will not keep — a dropped file then stays where it already is, and a screenshot is let go.

editor is which document is asking, because an app with two windows open has two answers and a bare call has no way to tell them apart.

accepts: fn(path: &Path) -> bool

Whether a file is a picture at all. Defaults to markdown::is_image, which guesses from the extension — an app with its own decoder, or one that wants a file the guess rejects, says so here.
