Hi ShaunMB7
There's a simple css fix for centering the images on the home page. To make changes to your css, check if your theme has a Custom CSS area in its theme settings area and add the following code:
.two_column_album .media-block {
float: none;
margin: auto !important;
}
If you can't find a custom css area in your theme settings, you can use a plugin - I'd suggest the Custom CSS module in Jetpack, which you already have installed.
The other issue in on mobile devices. What you're seeing instead of your album art is a WordPress shortcode.
[iron_discography albums="232" action_obj_id="345"]
This shortcode is compatible with your theme only and it tells your theme to display the album art and link. You theme, Lush, knows exactly what to do with this shortcode.
The issue you're having is that when you view your site on a phone, for example, it's not loading your Lush theme, it's loading a completely different mobile theme! Scroll down to the bottom of the site and hit the View Full Site link. All good, right?
To switch off this mobile theme, go into your WordPress admin area and go to Jetpack > Settings. Then untick Mobile Theme, and save.
That should fix it.
Let me know how you go.
