You uh... Can't put two images on one line like that. Well I guess you can, but it takes some complicated handling and parsing.
You should just create two image arrays...
Code:
<!-- Edit the url images to match yours
theImagesA[0] = 'images/statusicon/forum_old.gif'
theImagesB[0] = 'images/statusicon/forum_old2.gif'
theImagesA[1] = 'images/statusicon/forum_new.gif'
theImagesB[1] = 'images/statusicon/forum_new2.gif'
That's the best way of doing "two images".
