Quick ADVICE: the reference website (AYDRY) has a slider that is called "Slider Revolution"([!]). It is the JQuery version, it is not GIF based, and it is integrated in a Shopify website (not Wordpress). PROPOSAL: I suggest to use a similar Slider, but more Easily customizable and Free(gratis). It is called Smart Slider (demo at: [!]). You can see there are moving "titles" also there. I have not yet used this software but it has a graphical designer that hopefully it easy to use, and ... good news for you, perhaps, does not require to write "code". I have took some time to gather this information, I hope this finds you well.
