I have made a website using the split theme (fndaustralia.com.au) and replaced the stock photo with my own photo. The problem is now that depending on how I scale the website window I have bars appearing above or below the banner which looks ugly. The photo I am using is 7560 × 3916 pixels so surely should be enough to scale in whatever way it needs to be done. The problem doesn’t occur with the original split theme, so it must be something I have done wrong. Any suggestions?
