The API docs are the first point of reference for Java classes: BufferedImage

. If the Java Tutorials don't have anything, try Googling for information - there are plenty of sites with tutorials, code samples, etc.
The second one has a gumby.jpg image which is great, but I have no idea how to use any of that code!
A large part of learning to write code involves learning to understand and use (adapt) sample code. If you don't understand something, ask a question about it on the forum.
there has to be an easier way of making a single image have a transparent color...
To make a color in an existing image transparent, you need to set the transparency of every pixel that has that color. This involves checking every pixel in the image and adjusting those that have the color that you want to make transparent. If you think you can find a simpler way, by all means go ahead.
Those two links were just two that caught my eye when I googled for transparency in Java - there are hundreds of other links on the topic - as I already said, if you don't like the ones provided, you can find others. If you're lucky, you might find a full hand-holding tutorial that takes you through exactly what you want to do, step by step... unlikely, but possible.
Most people in your position will just ask questions about code they don't understand until they do understand it...
