Open up MS Paint. Open the picture's file. Use the select tool to highlight the part you want to save. Press "CTRL+C" (copy) and then make a new file. Press "CTRL+V" (paste) and crop it. Note: this is how I do it, you can select it and move it to the edge then crop it if you like. I don't like that way.
I don't think that your current pictures can be used due to the fact that your "text" is overlapping the ride cars.
