[Gimp-user] Scheme - image ID

["ugajin talktalk net" <ugajin talktalk net>]

I would likke to find the image ID from a Scheme script. 

(gimp-image-list) run in the Scheme console returns e.g. (1 #(5)) so I 
know from this that the image-id is 5, but if I have multiple docs open 
I may get the return value (2 #(8 5)). So how do I find and pass the 
correct image ID to a Scheme variable inside a script? E.g. (let* ( 
(img (cadr(gimp-image-list))) ) img ) now returns #(8 5). 

I believe the function needed may be (gimp-item-get-image item), but 
how do I find the item-ID and assign it to a variable?

Any help is appreciated.

Thanks
