Image Pairing and Memory Game


Hi Experts,

The image the size of Image Pairing and Memory Game are very small, however If I see Flashcards image size looks good.

How do I change the size of the image?  I saw the reply to use visual changes in CSS, when I did it is blurring the image instead of increase the size I want.

Please direct me how to get this done and if you give me code hook that would be helpful.
