I am displaying a large image in a front-page region. Currently I hook process_region in template.php, set a variable = theme('image'), and print it.
I'm thinking that rather than printing it from the hook, I'd rather add it to $page[my_region_name] and let it get printed when the template prints render[my_region_name].
Where do I add it, or what do I call to add it? I tried doing things in the hook like $vars[page][my_region_name][content][] = $my_themed_image, but that doesn't work.
