Anyone know the difference of these 2 pictures?

Firstly, please开发者_高级运维 go to this url: celebritywallpaperbase

picture #1 is Drew Barrymore smile

picture #2 is Debby Ryan

They are both 1920x1400 but Safari on iPad displays picture #1 with 960 x 720, whereas picture #2 is dislpayed with its actual size 1920 x 1440.

I am making a photolib project for iPad & I wish Safari always display my photos with their actual size.

Thanks in advance!

They have different DPI settings -

Drew's has 150 whereas Debby's has the more standard 72.
