[Plugin: Easing Slider] Alt Tag Slider Images

Good afternoon,

I am an SEO Technician and need to ALT tag images on this website: http://teethwhiteningin.co.uk/ (test website)

The thing is, the slider on the home page uses this slider plugin (easing-slider) and I cannot find how to ALT tag them how much i try.

HTML: <img src=”…” alt=”…” title=”…”/>

Thanks for the help in advance.
