Thank you for the answer!

The .zip file you are sending contains images. I uploaded these to storage in the appropriate folder. – OK

Where do I import the two .txt files? I tried the RevSlider import function (with slider_export.txt) but it throws an error message. 🙁

Forgive me for the question, but I haven’t used the revslider yet. Thanks!
