How to customize the linking file path in recorded photoshop actions.

Question

Hi,I have  a linked layer in a photoshop document in which I wanted to replace the file link associated with the layer. I saw such an option to relink, export, unembed linked graphics in InDesign but haven't found anything similar to it in photoshop. So, what I am trying to do is  - run this recorded action withapp.doAction("relink_1", "Default Actions");now I want to customize this relink to file with a different filename, is there a way I can modify / duplicate this action & pass custom parameters to it &start it with doAction again with photoshop javascript / applescript. Or, is there a way to do this without the use of actions [replacing the link in the linked graphic with javascript / applescript]

Very helpful post. Thanks for the share. One question though in the snippet I think he is grabbing the current selected layer & then replacing its contents. Can we do a select layer by name first & then replace / relink the file in the same way as suggested in the blog post.

var idslct = charIDToTypeID( "slct" );
    var desc18 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref15 = new ActionReference();
        var idLyr = charIDToTypeID( "Lyr " );
        ref15.putName( idLyr, "purplesock" );  // edit layer name
    desc18.putReference( idnull, ref15 );
    var idMkVs = charIDToTypeID( "MkVs" );
    desc18.putBoolean( idMkVs, false );
executeAction( idslct, desc18, DialogModes.NO );

or something like this...

Test whether a layer with a specific name exists?

What about right click on the layer with the linked image & replace content...?
