How to make a photo upload anywhere in the text in a textarea?

Question

PHP

How can I make sure that when uploading an image to the site, an img tag with a link to this image is inserted into the textarea, as it is presented on the toaster? Throw some lesson or code. Thank you.

I can assume that you need to "determine" the location of the mouse cursor in the text field.

function getCursorPosition( ctrl ) {
        var CaretPos = 0;
        if ( document.selection ) {
            ctrl.focus ();
            var Sel = document.selection.createRange();
            Sel.moveStart ('character', -ctrl.value.length);
            CaretPos = Sel.text.length;
        } else if ( ctrl.selectionStart || ctrl.selectionStart == '0' ) {
            CaretPos = ctrl.selectionStart;
        }
        return CaretPos;
    }
