How to obtain the 'current text box' where the input image is located?

Hi everyone.

I have selected all the content of the article and want to control the embedded images, so I need to obtain the text box where the images are located.
Surprisingly, The parent of the character  is “Story”, not “TextFrame”.

And parentTextFrames [0] may not necessarily be the text box where the image is located, It refers to the first text box that appears to be the story.

How can I get the current textFrame for 'story. allGraphics [i]'?

Thank you.

var d = app.documents[0];
var item = d.selection[0]
var story = item.parent;

if (story.allGraphics.length > 0) {
    for (var i = 0; i < story.allGraphics.length; i++) {
        var curFrame = story.allGraphics[i].parent.parent.parentTextFrames[0];
        alert(curFrame.constructor.name);
    }
}
