Just what I need but ...

I need a view program so I can view my images before I put them into photoshop cs6 to edit. I need to be able to view them at a ( fit to screen) then I need to be able to view them at 100 %. I want the option to use the (forward and back arrows) to scroll through my picture folder and I can not find that program for my iMac. I though this one was the one but each time I try to open images in this program it will crash :::… Does anyone know of a good program I can get to fit my needs ? Thank you so much Diana
