Using Lazyest Gallery version 1.1.0 or higher? You could benefit from the new Lazyest Gallery API by installing the Lazyest Widgets plugin.
In future releases I will not add any new widgets to the Lazyest Gallery core plugin. This Widgets pack is going to include them.
It is recommended to use these widgets instead of those included in the Lazyest Gallery plugin. Using AJAX to get the images will decrease the page compile and load time.

The following widgets are included in the Lazyest Widgets plugin:

• Recent Images Widget

  Shows the latest images you have added to your gallery.

  How does it work

  Each time, you upload a new image to your gallery, Lazyest Gallery adds a serial number to this image.
  This widgets will search images starting at the highest serial number and down.
  It will normally find the most recent uploaded image. However, it will not find the images with the latest image date.
  Images will be fetched by AJAX.

• Recent Images Slideshow

  Cycles through the latest images you have added to your gallery.

  How does it work

  Each time, you upload a new image to your gallery, Lazyest Gallery adds a serial number to this image.

  You can set the number of images to cycle through.

• Really Random Images Widget

  The Really Random Images Widget will fetch the random images by AJAX

  How does it work

  Each time, you upload a new image to your gallery, Lazyest Gallery adds a serial number to this image.
  This widgets will select a random number and return the image. The images will be stored in a buffer and will be served for all visitors in the next 10 minutes.

• Really Random Images Slideshow

  The Really Random Image Slideshow Widget shows random thumbnail images and is driven by AJAX.
  The Really Random Slideshow Widget does not show captions with the images.

  How does it work

  Each time, you upload a new image to your gallery, Lazyest Gallery adds a serial number to this image.
  This widgets will select a random number and return the image.
  This widget will get a new image after each interval.
  You can set the interval between requests for new images in the Widgets Admin screen.

• Latest Folder Widget

  The Latest Folder widget shows thumbnails and captions of the latest folders in your gallery, just like the folder listing in the gallery. The folder items will appear side-by-side.
