My slider was working fine and looked just like it does in your preview website. However, now my slider and the images are not displaying correctly. The image’s height is inconsistent, and the width is not the full length of the page. I read through some other forums, but I am very, very new to this and couldn’t figure out what to do to fix it. I just want it to display and look like it does on your example website.
My site is not live yet so I will have to send you my log in.
Sorry to hear of the problem you are having.
If you are using Jetpack plugin on your site then could you please try temporary deactivating it or its Photon module on your site?
This jetpack photon module is not updating the images stored on wp.com so to resolve the issue either disable this module or update the images on wp.com by contacting jetpack support team.
The recommended image width for the slider is 1920px X 550px so please make sure your slider images are at least of size 1920px X 550px
Also use the following plugin to regenerate thumbnails on your site.
