Just because people have viewed but haven't left a comment doesn't mean they didn't like the image, it simply means they looked and didn't leave a comment.

Not every image viewed warrants a comment.  Personally I only comment on images that strike me in a particular way IE: reminds me of something, something I felt stands out such as lighting or colours.  I like a number of images that I view, but I don't  comment on them all.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
