Hi,

Runing a code with your doc you need to notice possible occurrences (existing groups, anchored items, locked items, etc)

This one supposes to exclude grouped and anchored:

capset ();




function capset()


{


var


  mDoc = app.activeDocument,


  // anchored or grouped items excluded


  myGraphics = mDoc.splineItems.everyItem().getElements(),


  picContainer, gb, myCaption;


while(picContainer = myGraphics.pop() )


{ 


  // exclude empty frames


  if (!picContainer.graphics.length) continue;


  gb= picContainer.geometricBounds;


  // add a frame to to picture's parent, which is a Page


  myCaption = picContainer.parent.textFrames.add ();


  // set position and size of the caption


  myCaption.geometricBounds = [gb[2], gb[1], gb[2]+3, gb[3]];


  // add placeholder contents


  myCaption.contents = "Caption";


  mDoc.groups.add ([picContainer, myCaption]);


  }


}

thank u so much jarek.. your code is working fine..

now i'm getting one problem in this ,

i have document like book with left and right page..

when i run this script, it adds captions to all the images , but problem is ,the image which is in right-hand side page having caption in left-hand side page .

Because of the geometricBounds same for left and side page ...

for left-hand side images ,it is working fine.

so, caption has to add separately for each page images ..

      Hi,

      It should be:

      doc.groups.add([pic.parent, myCaption]);

      rather...

      Hi,

      3 remarks:

      - var pic is a graphic (pageItem.contents) so can't be element of group - use its parent instead of

      - you cant add textFrame to graphic container by the same reason ("picture's parent, which is a Page" not always true)

      - if pic.parent is anchored - adding textFrame and setting its gBounds wont work

      so

      - target your code to pic.parent

      - check if it is anchored before adding caption

        Just a remark, Jarek:
        You can add a text frame to a graphic frame by scripting with method add()
        You cannot do it in the GUI.

        But there is a practical problem using this with a graphic frame:

        The text frame is only visible inside the bounds of the graphic frame, because it is nested into the graphic frame.

        If you want the caption stay in the visible area of the placed image, no problem.

        If you want the caption below, above, left or right of the visible area, there is a problem using this method.
