Sample image sizes

All images are in 800 x 400 px and resolution in 72 ppi, but their weights are different in different optimization levels. (I have named the image with the quality (Q) and then the weight (KB)).

Generally I use Q30-40 for all sizes of the web images and resolution is 72 ppi. File format JPEG.
