i use CDisplay and some times ACDSee if the image isnt in jpeg( thats when i use ACDsee to convert the image )
and if the image if to big then you can go to options and make i fit the screen so you dont have to scroll down ( in CDisplay that is )
and you can just keep the chp zip if you use CDisplay....unlees there arent in jpeg,png and gif.....
but like i said thats when i use ACDSee to convert them to jpeg
