Randy the site looks great and supper easy to navigate.
I do have a minor critique though. This is an example of one
image I looked at.
The S&W J-Frame Pocket Holster Smooth Side Out Black has a
thumbnail image that is sized 238x178 and the actual image size
is 2032x1542. Making the image 1186.75 KB ( just over 1 megabyte)
Most of us these days are using broadband internet services but
there are others that are unable too. The load time on 1 image that
size is pretty lengthy at lower speed internet rates. If you put several
images on one of your pages and each are sized in that manner it could
take several minutes for slower internet connections to actually see all
the pictures, and by then some folks would have left.
My suggestion would be to rescale the actual image into 2 different sizes,
1 size for thumbnail and then one larger size such as 800x600 for folks
to get a better close up. Both those images would not equal the current size
of your main image that is being used.
God that sounds like rambling, hope you understood all that.
