160x600 you can use it in your sidebar 300x250 and 336x280 you can use it inside your posts and content or in sidebar too 728x90 use it in header and footer you will get good amount of money if you can get good amount of visitors to click your adsense images unit to get visitors you need high quality content ---- 336x280 worked for me good on most of my blogs
You probably won't make much either way. People are coming to your site looking for pictures. You have to connect user intentions to ads. If they want free pictures they are not likely to click on ads. It's really that simple.
Traffic from Google Image are peoples looking for images. So, IMO, an image only adunit may perform better.
