You can't use an 0.5-style expression inside the if= -- you need to replace your expression with a computed binding, like:

if="{{showImage(img_Path)}}"

See, for example: http://stackoverflow.com/questions/30607379/polymer-1-0-binding-css-classes/30607783#30607783

This is described in the migration guide under data binding:
