Adding Front-End Filter to Image Gallery - Sitefinity - Front- & Back-End Development

I found this Sitefinity blog entry on adding a front-end filter to the news widget and was hoping to apply something similar to the image gallery. I've added a drop-down list to the Simple List template, and like in the blog, the list is populated in the IntializeControl method with the categories pulled from a custom classification:

protected override void

InitializeControls(Telerik.Sitefinity.Web.UI.GenericContainer container, Telerik.Sitefinity.Web.UI.ContentUI.Contracts.IContentViewDefinition definition)

var productColorCategory = TaxonomyManager.GetManager().GetTaxonomies<FlatTaxonomy>().Where(t => t.Name == "product-colors").Single();

var productColors = productColorCategory.Taxa;

this.ProductColor.DataTextField = "Title";

this.ProductColor.DataValueField = "Id";

this.ProductColor.DataSource = productColors;

this.ProductColor.DataBind();

this.ProductColor.Items.Insert(0, new ListItem("Choose color..."));

base.InitializeControls(container, definition);

The problem I'm running into is figuring out how to make the image gallery update. The blog entry made it look simple enough, but then I found out that the image gallery doesn't have the GetItemsList method, or any similar method.

How would I update the query to include the category?

If it helps at all, we're using Sitefinity 7.0.

Okay, so I did try to edit FilterExpressions, but it looks like it gets used in the IntializeControls method, which doesn't do me much good. How could FilterExpressions be implemented so that I might be able to delay the execution to OnLoad? Or is there a way to filter images based on custom classifications by using the Libraries API?
