    The code responsible for this was a workaround for something else: ​Github link which point to Bug 1749.

    // bugfix for http://dev.jquery.com/ticket/1749
    if (el.is('.ui-draggable') || (/absolute/).test(el.css('position'))) {
        el.css({ position: 'absolute', top: iniPos.top, left: iniPos.left });
    }
    

    The fix itself exists since the beginning of time: ​Github Bug Fixed link for Jquery

    // bugfix #1749
    if (el.is('.ui-draggable') || (/absolute/).test(el.css('position'))) {
    
        // sOffset decides if document scrollOffset will be added to the top/left of the resizable element
        var sOffset = $.browser.msie && !o.containment && (/absolute/).test(el.css('position')) && !(/relative/).test(el.parent().css('position'));
        var dscrollt = sOffset ? o.documentScroll.top : 0, dscrolll = sOffset ? o.documentScroll.left : 0;
    
        el.css({ position: 'absolute', top: (iniPos.top + dscrollt), left: (iniPos.left + dscrolll) });
    }
    

    And was effectively just updated once, 7 years ago: ​Updated Link

    // bugfix #1749
            // bugfix for http://dev.jquery.com/ticket/1749
            if (el.is('.ui-draggable') || (/absolute/).test(el.css('position'))) {
                // sOffset decides if document scrollOffset will be added to the top/left of the resizable element
                var sOffset = $.browser.msie && !o.containment && (/absolute/).test(el.css('position')) && !(/relative/).test(el.parent().css('position'));
                var dscrollt = sOffset ? this.documentScroll.top : 0, dscrolll = sOffset ? this.documentScroll.left : 0;
    
                el.css({ position: 'absolute', top: (iniPos.top + dscrollt), left: (iniPos.left + dscrolll) });
                el.css({ position: 'absolute', top: iniPos.top, left: iniPos.left });
            }

    Make sure jquery-ui.css is referenced in your project!

    Per this question: Resizable, draggable object in jquery. Possible? if you simply include jquery-ui.css it will work. It solved my problem when none of these did. My code is simple:

    $(element).resizable().draggable();
    

    This was draggable but not resizable. Nothing else worked. Adding the CSS allowed resizing with no extra divs or code.

    Looks like it's because you're doing it on an <img>, which jqueryui wraps in a <div>, and then the draggable component of the image happens within the wrapping <div>.

    Try wrapping the <img> in a <div> (which if styled display:inline-block, will "hug" the size of the image in both x and y axes), make the <div> draggable (and therefore the enclosed <img> will be as well), and make the <img> resizable (and since the div hugs the image, it all sits nicely).

    Working example: http://jsfiddle.net/vrUgs/2/

    Resizable and draggable were causing all kinds of DOM shifting problems for me. There's a bug filed for this behavior; the temporary fix is to apply the following CSS, which worked for me:

    .element {
      position: absolute !important;
    }

    I was curious, here is working code that is draggable and resizable. jQuery:

    jQuery(document).ready(function(event){
       jQuery(".img").draggable().find("img").resizable();
    });
    

    html:

    <div class="img">
      <img alt="" src="images/hard-disk-fingerprint.jpg"/>
    </div>
    

    other stuff i noticed, take or leave it, as I do not know the work involved in changing your JS.

    first, all 'draggables' that are being dragged get a class of '.ui-draggable-dragging' which, you can use for your 'isDraggingMedia' logic potentially.

    second, to get the current position accurately, I recommend using the ui.offset{top:"",left:""}, possible altered with the ui.position{top:"",left:""} describing the position of the 'helper' object relative to the item being dragged.

     $('#div holding imgA+arrindexid').draggable({stop:function(event, ui){
    //isDraggingMedia = true;  
    //replace this with a $().is(ui-draggable-dragging) check if possible where it matters in //your other javascript.
                      // Set new x and y
                        resourceData[arrIndexID][4] = Math.round(ui.offset.left / currentScale);
                        resourceData[arrIndexID][5] = Math.round(ui.offset.top / currentScale);
        }}).find('img').resizable();

    If you apply the resizable first, you can then apply the draggable to the img's parent; which is the new div created by applying resizable.

    chartImg.resizable({ animate: true,
                ghost: true,
                handles: 'n,s,e,w,ne,se,nw,sw',
                start: function (event, ui) { startResize(event, ui); },
                resize: function (event, ui) { monitorResize(event, ui); },
                stop: function (event, ui) { stopResize(event, ui); }
            }).parent().draggable({ containment: $(".chartPane") });
