Layout in UPG is used to change the theme/looks of the post gallery submitted by user. Using PHP/CSS code of your own the look & feel of gallery can be changed completely but for this you need to use personal layout.
Some of the layout is already attached with the plugin.
We have 3 (Three) types of layout.
Grid layout is the layout where all submitted images/post are shown together. In short it is the page where [upg-list] shortcode is used. layout parameter is used inside shortcode to change layout else it will pick the default layout from UPG settings. Files are stored inside wp-upg/layout/grid/ folder.
When user clicks on the image/post, the detail page of post is opened. That page we call it as preview layout. For eg. Single product/image full description page is preview layout. The layout of the post can be different in each post. It can be modified by editing the post. Files are stored inside wp-upg/layout/media/ folder.
This layout is used to change look/feel of user submission form. The layout parameter is used inside [upg-post] shortcode. The files are stored inside wp-upg/layout/from.
