This works well in ASP NET webforms   Change the script to   lt img src      imagePath    chevron-large-right-grey gif  alt           I have a master page for each directory level and this is in the Page Init event    Dim vPath As String   ResolveUrl    Images        Dim SB As New StringBuilder     SB Append  var imagePath       amp  vPath  amp             ScriptManager RegisterClientScriptBlock Me  Me GetType     LoadImagePath   SB ToString  True    Now regardless of whether the application is run locally or deployed you get the correct full path  http   localhost 57387 Images chevron-large-left-blue png

Good question    When in a CSS file  URLs will be relative to the CSS file  When writing properties using JavaScript  URLs should always be relative to the page  the main resource requested     There is no tilde functionality built-in in JS that I know of  The usual way would be to define a JavaScript variable specifying the base path    lt script type  text javascript  gt     directory root    http   www example com resources     lt  script gt     and to reference that root whenever you assign URLs dynamically

JavaScript file paths  When in script  paths are relative to displayed page  to make things easier you can print out a simple js declaration like this and using this variable all across your scripts   Solution  which was employed on StackOverflow around Feb 2010    lt script type  text javascript  gt     var imagePath    http   sstatic net so img     lt  script gt    If you were visiting this page around 2010 you could just have a look at StackOverflow s html source  you could find this badass one-liner  formatted to 3 lines      in the  lt head   gt  section

A  proper solution is using a css class instead of writing src in js file  For example instead of using     this  css  background    url     Images filters collapse jpg        use     this  addClass  xxx      and in a css file that is loaded in the page write    xxx     background-image url     Images filters collapse jpg
