I don't know why enable image shadow effect on my blog. Anyway I can disable that option by hand in CSS code adding on my template.

Simply you can add this code on "Blogger template designer" -> "CSS adding".:

.entry-content img{  
 box-shadow: none !important;  
 padding: 0px !important;  
 border: 0px !important;  
 }
