The tutorial says " you need to crop the image intro 4 parts: top left (512x512), top right (512x512), bottom left (512x256), bottom right (512x256). In order to do this, you need to play with selection. Start by making a rectangle somewhere at the middle (you can move it later) and, by checking the window title, make sure its size is 512x512 (512x512 for the 2 top images, 512x256 for bottom). Once you do so, right click on the selection you just made and drag it to the top left corner so that the title shows something like "<filename> - IrfanView (Selection: 0, 0; 512 x 512; 1.000)" (as you can see 0, 0 is important here) - picture 3. Now go to Edit -> Crop selection and save the file as TGA. This is the first out of four parts so lets continue - open the main picture again and do the same thing 3 more times with proper sizes and positions ("0, 0" for the top left, "512, 0" for top right, "0, 512" for bottom left and "512, 512" for bottom right). Take note that one pixel less/more than it should might result in your whole loading screen not showing so be careful"
It means that I have to crop my image in 4 parts,but when I crop the image I still see the full image with my crop selection. if i register I register the full image and this is useless beacause i need only 1/4 of the image. So how to crop a part of the image a delete the other 3/4.
Hope that is better said like this.
