I agree. The photos in the OP are too big (I think that you can put a medium size photo in the BlogSpot page, and when you click it, it goes to to the full resolution image.)
Also it needs some minimal captions, to explain what is happening. The post at http://reddyraveesh.blogspot.com is much better, but I think it need even more text.
