How does George MacDonald Fraser use imagery in Flashman and the Mountain of Light: From the Flashman Papers, 1845-46?

Examples of Imagery:

Elspeth, I may tell you, speaks only English—well, Scotch, if you like—and enough nursery French to get her through Customs and bullyrag waiters, but anything the Queen said, however wild, always sent her into transports of approval.

"George, I ain't puffing myself, but I'm not unknown over there! Man alive, when we had a garrison in Lahore, in '42, I was being trumpeted all over the shop! Why, you said yourself the fewer who knew Iflassman was back, the better! They know I'm a soldier, don't they—Bloody Lance, and all that rot?"
