Is there a way (or an editor) that allows me to link an image/files/http links from within a source file (*.java for instance), sort of like a rich text document?

You probably have tools and plug-ins that allow easily to see the Javadoc of your file.
One good example of mixing images and links in Javadoc is JRootPane
