I'm not familiar with Kentico but these solutions might help. They may not address your problem specifically but might aid in a solution.

CMSEditableImage Extension Method

I came up with a way to check this, I added an extension method for the CMSEditableImage class that takes the CurrentPage PageInfo object to check the value of the editable region, don't know if this is the best way or not, but here's the code.

public static bool IsPopulated(this CMSEditableImage editableImage, PageInfo currentPage)
{
    bool isPopulated = false;

    string value = currentPage.EditableItems.EditableRegions[editableImage.ID.ToLower()].ToString();

    if (!string.IsNullOrEmpty(value))
    {
    value = value.ToUpper();
    isPopulated = (value == "") ? false : true;
    } 

    return isPopulated;
}

JavaScript Method

The webcontainer needs an id, example:

Headline

Then I have a small javascript function that is attached in an external js file:

/* Hide Webcontainer via javascript if empty*/
function hideLayer(element) {
    elem = document.getElementById( element );
    elem.style.display = "none";
}

Now in the wep part configuration, at no data behaviour, you uncheck the checkbox and call the js function by entering following script in the no record found text: hideLayer("webpart-header");

Whereby webpart-header the id name of your container is. You could also have a more complex

structure here.
