how can I load an external picture/image file to screen?
I want to use locator() then to get coordinates of that picture...
...in other words I want to use R to do some measurements on a picture.
Therefore I need to load the image into R display,
and that displaying needs to work together with locator().
How to do it best?
At the moment I need to be able to read in *.png files,
but if *.jpeg or other formats also will be supporttzed, this would be fine.
