Scenario, You're using standard Wordpress blog and it will display a lot of graphics. With Adsense blended inside the content. Which one do you prefer ? Option A --------------- Resized the graphics to 450 pixels width and reduce the quality to fasten the loading, and blend Adsense Ads with them, but after the viewer scroll down, Adsense ads will be not visible unless you opt for double skycraper. Option B --------------- Use thumbnails ( 128px width ) and load them in the table with Adsense blended together. User click the link, but the ad will be visible all the time because the user will click thumbnail and popup new window to view the high res version..and still not leaving the original page.
