Examining a blogger template's img tag (data:post.thumbnailUrl) i've approached a mystery.

An inline style tag controlling the width, margin and heigh perimeters are getting added to my img element.

They are auto adjusting the images ratio to fit a smaller size.

But I can't figure-out where this style tag script lives and how it's happening in my template. My template has no special javascript or jquery scripts.

The full size images in the single posts page don't have this style tag.

Is this a css or xml feature?

element.style {
margin-top: 0px;
width: 301.0033444816054px;
height: 200px;
margin-left: -0.5016722408026908px;
}
