You can add several different filters to your gallery thumbnails in FooGallery Pro. The filter you select is applied to all of the thumbnails. In other words, you can’t select different filters for each thumb. The filter will not be applied to the full-size images.
You can see the different filters available to you on the demo page.
Applying Different Thumbnail Effects
To make use of this feature, edit a gallery, then find the gallery settings.
Under the Appearance tab, you will see a setting called “Thumbnail Effect”.
You will be able to select the effect you would like to apply. There are 12 to choose from.
Once selected you can preview the gallery, and when you are happy, save the gallery.
