For the first part of your question - Answer is -- thats referencing problem , Image is not found in the drawable folder. as appbee suggested , put ur image in drawable folder i.e. res/drawable in ur workspace, if that folder is not there , create it and put the ok.png / ok.jpeg in it.
Second part I did not get the problem exactly , I think again it might be referencing problem , check the id's u have declared in your xml files. U cannot modify R.java , clean up the project and resolve all references and try again.
