Location for public photo in homepage

Hi,

I want to edit the display and can someone pin point me where i can edit it?

example:

the default code for image is

<img class="bx-img-retina" src="xx"src-2x="xx" />

and want to change it to

<img class="bx-img-retina homethumb" src="xx" src-2x="xx" />

Try the template for photos in the photo module.

Thanks.

For those who want to edit it to make smaller
