It's probably the case that if you can't run functions on sample
images, you won't be able to run them on your own images.

What command caused this error? Sending error messages without the
commands that caused them is not too useful.

What is the command you are trying to run?
For readImage(), instead of doing this:
> f = system.file("images", "lena.gif", package="EBImage")
> lena = readImage(f)
system.file() is used to refer to files that are part of installed
packages. When you want to refer to your own files, you can usually
just put in the full path to your file instead of the system.file()
