Sorry to answer my own question. Just thought I'd share that JLabel no longer scales itself to fit the image dimensions. In short, just replace the html line with
html=sprintf('<html><img src="file:./%s" width="%d" height="%d">', filename, imageWidth, imageHeight);
Obviously, replace these variable names or assign them values. You can also use java's bufferedimage class with the method getWidth() and getHeight() to find these dimensions
