Hello,
in line 260 of "template/../../productpagedetails" i have change "<1" with ">=1".
This because if I have 10 product in stock, and 5 product in order, the result is 5<1, and in this case the function don't display availabile's image.
With this mod the function display the image...
Sorry for my bad English
these images are for "out-of-stock" products and not for shipping time or something else
