I am trying to load multiple jpeg files into java using BufferedImage. I can load and display one file using;
BufferedImage loadImg = loadImage('trial0001.jpg);
When I try to add a second file, all I get is error messages.
Thoughts please.
Thanks

First off, thanks for taking time to reply.
I did look at the tutorials. The first projram worked (load then output one jpg). I tried to upscale and lost it. My goal is to get about 30 to 40 jpgs to load then display in jpanels. Then I'll manipulate the files. Here is the code so far. I included the errors in the code. They are repetitive.
