You may never go wrong with Google places optimisation once you get your website ranked where you want it. If you are increasing your site then its success is degrading. If you allow your site to slip down-then someone will start standing above you. Add new, appropriate information regularly and always work on improving your links.
To have SE traffic out of your pictures, take advantage of the ALT tag. The ALT tag allows you to include text to the image’s information, which suggests search engines can appropriately index your image.
