Howdy flamencoagenda,
Welcome to our support forums and thanks for reaching out to us. I’ll help you out on this one!
From what I see in the source code of your site, the width of the image in list view is limited by the CSS of your theme. On line 493 of the theme stylesheet (wp-content/themes/sixteen/css/main.css) you have the following:
.search .wp-post-image, .archive .wp-post-image {
...
max-width: 50%; // this is the line affecting images width
...
}
You can edit that line directly in the CSS file or add the following code just to adjust this for events list view:
.tribe-events-list .tribe-events-event-image img {
max-width: 100%;
}
Please let me know if this gets it right and if you have any follow-up questions,
Best,
Nico
