you where all correct, I checked bounce rates and its well over 60% meaning, that amount of my traffic gets confused on the homepage and quits it. So I put in mind to do some modifications to make my blog more viewer friendly.
I implemented read more link at the end of the excerpt on the index page only. I also decided to show 1 photo per excerpt if its possible
also I changed 'permalink' to 'photos' - so that user knows that post contains photos.
What do you think? is it good now?
