SmugMug provides unlimited storage space and unlimited trafffic.
You can track traffic for every gallery and every image or video. We'll show you data for the current month, as well as the prior month.
You must be logged in to view your viewing stats. Click on the Tools button near the top of your SmugMug pages. Under "My Account", click Go to Control Panel.
At the top of your Control Panel you'll find a Stats tab with a link entitled more details. Click it.
It will show a graph for each of your galleries with the number of hits shown for each photo display size or video clip resolution.
We also include photo views to photos you have posted externally, such as in a blog or forum. If you post a custom size, we count hits as though they were for the next largest display size.
I want stats on each photo in the gallery.
Simply click on a graph like the one you see above (but not on the gallery title above the graph).
Or, select View Stats from the Tools Menu. The following display will appear:

C. Ratio stands for Conversion Ratio
The conversion ratio is simply the number of larger hits divided by the number of thumbnail (both sizes) hits.
The higher the number, the more people are seeing larger-than-thumbnail versions of your images.
Where are all these hits coming from!?
