I have this code for loading images from within a web start Jar. I'm wondering how good it is and what I can do to make it better.
The last function loadImg is really what I have problems with. I first load the image as an ImageIcon to not raise a security exception. Secondly I draw that Image into a BufferedImage because I can't cast it directly, as it's giving me a ToolkitImage instead of an Image. Updated with information gained from another thread on JGO.
Usage is :
BufferedImage img = ImageLoader.loadImage("data/images/", "test.png");
or
BufferedImage img = ImageLoader.loadImage("test.png");
