285026 Modify script to blink images

This should be an easy project for a good javascript programmer. I have an existing javascript (see attached) that works well for image hovers. I want to add an additional feature to this script. I would like the ability to have an image rotate between the normal and hover image X amount of times, then it just functions normally. Example: When the page loads, the image switches between the normal image (_nm) and the hover image (_hv) 10 times, then functions normally. I should be able to set the variables in the javascript for the number of times to swap the image, and the time duration between switches. Take a look at how the existing script functions, then I'm open to any ideas you have to solving this problem (ie. like setting a class or div). Post any questions in the comments. Thanks!
