Convert embedded image to a linked

Pasting a previously placed image would give you full res -- in essence you are pasting the pointer to the image...

Bob's method is better if you can see filenames in the Links panel. But if you can't see any links, which is usually the case when images had been pasted into InDesign, then the script can be used.

I use the script listed below for that.

Peter

// Unembed images without links: write them to disk and create a link
// Images are saved as JPEGs in the document's folder using the name 
// "unembedded_" followed by a sequential number

try {unembed_images ()}
    catch (e) {alert (e.message + "\r(line " + e.line + ")")};

function unembed_images ()
    {
    // Alternative: baselineEncoding
    app.jpegExportPreferences.jpegRenderingStyle =  JPEGOptionsFormat.progressiveEncoding;
    // Options: maximum, high, medium, low
    app.jpegExportPreferences.jpegQuality = JPEGOptionsQuality.maximum;
    // Any resolution
    app.jpegExportPreferences.resolution = 300;
    var output_folder = String (app.documents[0].filePath);
    var g = app.documents[0].allGraphics;
    for (var i = 0; i < g.length; i++)
        {
        if (g.itemLink == null)
            {
            var image = File (output_folder + "/unembedded_" + String (i) + ".jpg");
            g.exportFile (ExportFormat.jpg, image);
            g.parent.place (image);
            }
        }
    }

Select the links in the links panel and from the links panel menu select unembed link.
