When you develop DNN Skin, always keep in mind you need to have put <%= SkinPath %> for your CSS and Images in your DNN skin development
for instance,
Put an image into the Skin, same directory with Skin ACSX but with a sub folder to put all skin’s images
<img src=”<%= SkinPath %>images/button_calendar.gif” border=”0″ alt=”Start Now” />
Put a CSS or JS file into Skin
<
link rel=”stylesheet” type=”text/css” href=”<%= SkinPath %>skin.css” /><
script src=”<%= SkinPath %>runactivecontent.js”></script>
