The Loaded effect is the animation that the thumbnail image uses ones it is loaded. This is different to the Loading icon – often a circle or dots moving around – which shows that the image is currently loading. Once it has loaded, however, the thumbnail uses a Loaded Effect to display itself in the gallery.
FooGallery Free can be set to None (no effect is used) or Fade In. FooGallery Pro has 10 different options from which to choose. You can see the demos here. To see the effect properly, you can scroll to the next page for each gallery.
Applying Loaded Effects
Loaded Effects are available in FooGallery Free and Pro, under the Appearance settings. To apply a loaded effect, go to the Appearance tab for your gallery. If you click on the Loaded Effect field, you will be able to select the effect you want to use.
