hey an element grid is not a carousel
i think u're looking to create a carousel:
https://laytheme.com/addons/carousel.html
sorry for the late response
and can u update lay theme and the carousel addon? maybe it was an issue with that, i just fixed something
they are two big, is there any way to force the wp to resize the pictures?
do u mean they are big in data size, like 5Mb or like many megabytes?
or do u mean they are too big on the website, meaning the dimensions in the browser?
