I've just changed to eclipse an I'm used to manually managing my project structure with Windows filesystem (compiling my .java files into bin with a batch-script). Whenever I wanted my classes to use a .png-file, I simply put this file into the .bin folder.
If I put my .png-files in the bin-folder of the eclipse project as I'm used to, the classes will be able to load the pictures just fine. But sometimes, I don't know when, Eclipse simply deletes the bin-folder and creates a new one based on the contents of the src folder (which doesn't have my .png files). Putting the files into the src-folder (again, manually from the windows file-system) doesn't actually put them in my Eclipse project.
So what I want to ask is: Why/when does Eclipse completely rebuild the bin-folder. And how can I put resources, like .png-files, into my Eclipse project?
