Gallery: Move Gallery Up over Description. 5 thumbnails in Row

Hello @kolumb55.

Please be informed that in the first case you would need to customize the files of your theme. So for me to guide you properly, please, provide the name of the theme that you use. As for the thumbnail quantity, I may suggest you apply custom CSS under the Dashboard > Appearance > Customize > Additional CSS to change the max-width so all the images can fit in one row. Here’s an example:

.gallery-columns-4 .gallery-item{
  max-width: 120px;
}
