html - Fotorama thumbnail images not displaying -grey block & no image on click -

i'm having display issues fotorama 4 , cannot head around how fix it.

when preview code in codepen.io looks fine when put wix website working on client of thumbnails grey blocks , when click on them no image shows.

i'm thinking maybe i've messed somewhere. customised regular code had text display on first image , text disappear on hover. still new customising code suggestions helpful!

here customised code using: http://cdpn.io/dyfus

if have idea issue please point out , leave tested correction below.

your layout wrong. replace this:

<img src="1.jpg"><img src="1_thumb.jpg" /></a> <img src="2.jpg"><img src="2_thumb.jpg" /></a> <img src="3.jpg"><img src="3_thumb.jpg" /></a> 

with this:

<a href="1.jpg"><img src="1_thumb.jpg" /></a> <a href="2.jpg"><img src="2_thumb.jpg" /></a> <a href="3.jpg"><img src="3_thumb.jpg" /></a>
