trouble with logic in java

I am trying to get this program to show two pictures and check if they are the same picture, i am having trouble getting bildeSjekk() to do this, it shows all pictures and if you double click a picture it removes it, first i need to store the previous instance of the int i, then when teller should become two when two pictures have been revealed, and then i will use current int i and int temp in the int array index and check if the value is the same. It's a Picture memory game.

You might like this related memory game that uses JToggleBUtton and Unicode glyphs instead of pictures.

Addendum: As an aside, you may get more helpful answers if you prepare an sscce that doesn't depend on a large number of inaccessible images. As an example, RotatableImage is a simple, static class that can be adapted as required.
