A few pointers which may help you!
View full size pictures – If you are viewing an individual coin (eg http://www.ringramcoins.com/unite-11418.html ) and click on view large image it will open in another window. If you wish to view the other side of the coin you can then click on the first window and click on view large image on the other side (without using the back button).
Grid view – To view larger thumbnails of all the coins (eg Crowns: http://www.ringramcoins.com/coins/crowns.html ) then go to the mid/top of the screen and click on grid view – which is a cube of 9 small circles.
Also if you would like to view a different number of coins in one go you can click on the bottom right of the screen and you have a choice of whether to view 30,60,120 or all coins in one go.
