2. Add Image widget in Designer tab
3. Add "PrintString" node and "Get Image widget variable"
4. Connect the output pin of "Get Image widget variable" to the input pin of "PrintString" 
5. Connect the "PrintString" node to "Event Construct"
6. Change to Designer tab, select and deselect the Image widget name from the details panel (not from the hierarchy view).
