Handle cases where there are multiple images in the same <div> on an article page. Refactored the code to handle images into a separate method so that it can be re-used in this situation. Also changed how the image tag is found as in the case where there are multiple images the img tag does not contain the "thumbimage" class.
Genericised the finding of images to download because some divs contain multiple images. This handles cases with <div><div><div class="thumbinner"> - previously it was hardcoded to a depth of 2 divs.
