I used a proximity conditional to enlarge the dot when the mouse was nearby and cause the images to load.
I then used much of what we covered in Lab 3 (with sounds) to make each thumbnail a button to load the thumbnail image into the main image area and play the narrated sound.
At this point, the program only works well through the first cycle. After one set of images load and the sound plays, the dots do not reappear. The other country images will load, but I have not completely reset the map so that the dots return as they should and the images are all a bit off on loading. For example, the mouse may be over Vietnam when the Brazil images load.
