Does anyone know if there's a simple way to change a picture on mouseover that works in Firefox? My game is transitioning to 15 years in the future so I want their cast picture to have their main PB and then their younger pb upon hovering, but every code I've seen is either too long to put 45-70 times in a cast list, or just not working in Firefox. =\

Any help would be greatly appreciated.

Can anyone tell me why when I use journal watcher to archive icons from one journal then upload the zip file I get to another account, the new journal will have three to eight icons less then the old journal?
