I got stocked in Fike Chooser. It suppose to load the image to JFrame,
and than I need to work with an image. If it doesn't choose right extension (jpeg, gif, etc) htan JOption window pop=ups with message "WRONG FILE". Also when it loads to JFrame it has the button "save", so it should save in in the disk.
I've got lost in loading the image via File Chooser into JFrame. Please, HELP!!!
