Can I manually set the height of the slide show / promo?
Yes, in js/general.js there are settings for the cycle plugin, you will see a height setting.
Before 6.22.10 – it will be set to ‘auto’ – change that to 400 but do not use quotes like you see on auto.
400 is just a sample height, you may need more or less.
Be careful to leave the comma after the number
