IG5 Alpha Five v11 Image Gallery Filter Argument

By default, when you open an Image Gallery, all of the images in the specified folder as shown. However, the Image Gallery supports a filter property that allows you to apply a filter to the list of files in the folder. For example, if you specify a filter of image_bathroom_*,image_kitchen_*, then only images that start with 'image_bathroom' or 'image_kitchen' will be shown in the Image Gallery.
This ability to filter the list of images shown in the Image Gallery dynamically greatly enhances the flexibility of the Image Gallery. (Requires build 3815 or above)
