Here is a tip to help you with the Virtual gifts.   If you dont like the default images that come with the plugin, you can delete them all.

But if you do delete them all, make sure after you add the new images that you refresh your cache, otherwize when you send a gift you will get a white page with this text.

{"message":"Gift has been sent"}

once you fresh your cache then you will begin getting the normal confirmation message display.
