The implementation of get_displayed_browse_products doesn't work for COISS. The problem is that the medium preview image has a .jpg extension and the full preview images has a .png extension. Thus you can't do the string replace in this code. The effect is you can't click on a COISS image on the detail page and get the full image. The code will need to be changed to get both the medium and full browse products from get_pds_products.
