PhotoShow can auto-generate thumbnails of images, display the EXIF data and allows others to comment them. HS Gallery is a free plugin for Elxis 4.x which uses Highslide JS and allows you to show image galleries inside articles as slide show, clicking on the thumbnail of the first image, by a selected order (by name, newer images first, older images first).
Tip: For making plugin to display images fast, run it at least once after setting a folder of images, in order to create the thumbnails of all images. This involved migrating the content of this blog to the WordPress blog built in to the site. Thumbnails are creating automatically with the same file names as the large images into an auto created folder named thumbnails, subfolder of each images folder. The plugin supports gif, jpg, jpeg, png images file types, is RTL compatible and mobile friendly.
