All right!
I can get the images to display on my pages on the sandbox using the code

<img class="pull-left" src="<?php echo get_stylesheet_directory_uri(); ?>../coreImg/coreLogo100x100px.png"/>
hower once the site is live the images no longer display (yes I checked, they are there). My test site is at

and also and I google this first as well I can't get the background images to display at all, sandbox or live. And of course the code I tried was:
border:2px solid #000;
I added the border to see if it would show up. It does. the images don't, w/either one of the tags.

Am using root retlehs. I have attached an image of what I get as well. Anyone has run across this problem & solved it please?

Thank you all.
