Inline image_in render; fix example-click misrouted to generate

The previous deferred-render pattern (image_in declared with render=False
then rendered inside a column after gr.Examples) caused gr.Examples to
wire its click event to the next registered handler (run_btn.click ->
generate), but with only [image_in] as the input list. That produced
"generate didn't receive enough input values (needed: 6, got: 1)".
Declaring image_in inside the column directly and putting gr.Examples
immediately after fixes the wiring.
