I think I've solved that problem: sorry for posting the question. Just
to summarize:
if I have a.jpg and b.jpg in a directory and I have CmsObject for
a.jpg and I want
to get the contents of b.jpg:
	

			// Start with imgObjectA, the CmsObject corresponding to 'a.jpg'.
			// Want to get byte[] of the contents of 'b.jpg' in the same directory.

			

			String folderUri = imgObjectA.getRequestContext().getFolderUri();


			CmsResource folderResource = imgObjectA.readResource(folderUri);


			// get path to folder relative to root of site 
			String folderSitePath = imgObjectA.getSitePath(folderResource);
			CmsFile fileB = imgObjectA.readFile (folderSitePath + "b.jpg");
			byte[] contentB = fileB.getContents();


imgObjectA.getRequestContext().getFolderUri(); was the vital method I
was missing.
Thanks,
Joe.
