at first : I had problem to read image ina javascript like this:

var image = "/images/my_image.png"

so I try another way. But is this way of how to check the real path correct? Thank you for your comments.

var string = location.port;
var full_url = "";

if(string != ""){full_url = document.domain + ":" + string;}
else{full_url = document.domain;}

var image = "http://"+full_url+"/images/my_image.png"

What do you mean with "I had problem to read image in a javascript like this."? Can you explain further? That should work.. – Jonas Grumann Mar 03 '15 at 12:36
"I had problem to read image in a javascript like this." -> I did mean that I had problem to load image with my first code ... in this way. (excuse me for my english gramma) – Takeshi Mar 03 '15 at 12:39
Can you show us how you're loading image? – Mindaugas Večkys Mar 03 '15 at 12:41
