Go to front-end wishlist or cart and show page source. You can find this fragment code (URL of an image) in page source:
/components/com_jshopping//images/arrow_left.gif
/components/com_jshopping//images/arrow_right.gif
Problematic code is in file \components\com_jshopping\templates\default\cart\cart.php
on row 230:
<img src = "<?php print $this->image_path ?>/images/arrow_left.gif" alt="<?php print _JSHOP_BACK_TO_SHOP ?>" />
and on row 238:
<img src = "<?php print $this->image_path ?>/images/arrow_right.gif" alt="<?php print _JSHOP_CHECKOUT ?>" />
and in file \components\com_jshopping\templates\default\cart\wishlist.php
on row 149:
<img src = "<?php print $this->image_path ?>/images/arrow_left.gif" alt = "<?php print _JSHOP_BACK_TO_SHOP ?>" />
and on row 157:
<img src = "<?php print $this->image_path ?>/images/arrow_right.gif" alt = "<?php print _JSHOP_GO_TO_CART ?>" />
In these troubled lines should be replaced
<img src = "<?php print $this->image_path ?>/images
with
<img src = "<?php print $this->image_path ?>images
