Inserting images

Image path

Alt and title attributes form file labels.txt

If you insert the path to the directory with images, then you can specify the alt and title attributes for each image in the file labels.txt, which should be placed in the directory near with the images.

The contents of the file must contain information in the following form: file_name.webp | alt attribute | title attribute. For each image, the information is contained in a separate line. There is no need to put the | character at the end of the line. Title for images can be omitted, then the string will look like image_2.webp|alt for image_2.

image_1.webp|alt for image_1|title for image 1
image_2.webp|alt for image_2
image_3.webp|alt for image_3|title for image 3

Список

Comma-separated list of file paths

HTML code between tags

Preset layouts

Default layout for tmpl=default

You could have used other plugins earlier that use the same shortcode 

Video files in the gallery

The plugin supports HTML5 - mp4, webm, ogv video files. All the ways to add files to the gallery define video files. For the video tag, according to the HTML5 specification, you need to specify the poster attribute - an image that will be shown as a splash screen before the video starts playing. The poster image file for the video must have the same name as the video file itself and be located in the same folder. Then the plugin will find and use it automatically.

Creating your own image gallery layouts

The output layouts are located in the html plugin content folder - plugins/content/wtcontentimagegallery/tmpl. Copy the file default.php , rename it and embed your HTML layout and javascript. It is advisable to connect files using Web Asset Manager, place the scripts themselves in the media folder of the plug-in, or design them with independent plug-ins, like WT JSWiper.
