Script to find image box within a table (data merged)

This should help.

function main(){
    //-----VARS-------//
    var doc = app.documents, gfxs = [], n = 0, p, c, gfx, os, cl;

    //Exit if no doc open
    if(!doc.length) return;
    doc = doc[0];

    //Exit if object style not found
    os = doc.objectStyles.itemByName("shadow");
    if(!os.isValid){
        alert("An object style named \"shadow\" is needed to run teh script.");
        return;
    }

    //Let's loop through the array of graphics objects inside docs
    gfxs = doc.allGraphics;
    n =gfxs.length;
    while(n--){

        //let's climb up to what should be a cell.
        gfx = gfxs[n];
        //The container of the image
        p = gfx.parent;
        // a character containing a anchored fralme, a cell or a table object or something else
        c = p.parent; 
        //a cell or a table object or something else
        cl = c.parent;
        
        //If the graphics hierarchy returns a cell or table object, let's apply object style to the graphic
        if(
            /^(Cell|Table)$/.test(c.constructor.name) 
            || 
            /^(Cell|Table)$/.test(cl.constructor.name)
        ){
            p.applyObjectStyle(os)
        }
    }


}

//run
main();

[EDIT] Fix case with graphic cells and possible 1 cell only tables.

Hi Loic! Thank you for helping! I'm looking for only those mounted by the merge. For example, only the images that appear in that top frame with the text underneath.
