Markup dimensions in InDesign file

In progress now. Uses same interface with a few changes. I will post here and in Illustrator section when done.

I asked the question and discovered the answer!

The script below is the correct one.

Copy and paste the following lines in notepad and save as"labelImageSize.jsx" (must include the .jsx extension, obviosuly). Also, make sure you have "Arial" font installed on your machine, otherwise replace "Arial" with a font you have installed.

Finally, by default the dimensions won't print. If you want them to; check the "Print Layer" option within "ImageLabel" layer.

SCRIPT STARTS AFTER THIS LINE:

----------------------------------------------

//DESCRIPTION:Label image with its size
// Jongware, 13-Jan-2012
// No Guarantees, Etc.

if (app.documents.length && app.selection.length == 1 && app.selection[0].hasOwnProperty("paths"))
{
if (app.version < 6)
labelItem(app.selection[0]);
else
app.doScript(labelItem, ScriptLanguage.JAVASCRIPT, app.selection[0], UndoModes.ENTIRE_SCRIPT, "Label Image Size");
} else
{
alert ("No valid selection.\nPlease select one single object with the black arrow before running this script.");
}

function labelItem (item)
{
// Save current selected layer because adding one will make it active!
activeLayer = app.activeDocument.layoutWindows[0].activeLayer;
// Make sure the layer "ImageSize" exists

app.activeDocument.layers.add({name:"ImageLabel", ignoreWrap:true, layerColor: [90,192,90], printable: false});
