From this link:
http://www.sitefinity.com/documentation/documentationarticles/developers-guide/sitefinity-essentials/modules/media-modules/images/managing-albums/querying-albums

Upgrading to 5.1 seems to have broken the ability to do App.WorkWith().Albums().Images

'Telerik.Sitefinity.Libraries.Model.Album' does not contain a definition for 'Images' and no extension method 'Images' accepting a first argument of type 'Telerik.Sitefinity.Libraries.Model.Album' could be found (are you missing a using directive or an assembly reference?)

thx

Oops, let me clarify, it's done by this exact code.

public static List<Telerik.Sitefinity.Libraries.Model.Image> GetImagesByAlbumName(string albumName)

var album = App.WorkWith().Albums().Where(a => a.Title == albumName).Get().FirstOrDefault();

if (album != null)

return album.Images.Where(x => x.Status == ContentLifecycleStatus.Live && x.Visible).OrderBy(x => x.Ordinal).ToList();

else

return new List<Telerik.Sitefinity.Libraries.Model.Image>();

album.Images generates the error.

Hi, Chris.

In order to decrease the consumed memory and increase the overall performance of Sitefinity, several properties (in-memory collections) of given classes were replaced with extension methods that return the same data via IQueryable collections. See this page from the documentation.

One of these was the Album class. So Images is now an extension method of Album as shown here.

So your code needs to change just a bit:

public static List<Telerik.Sitefinity.Libraries.Model.Image> GetImagesByAlbumName(string albumName)

var album = App.WorkWith().Albums().Where(a => a.Title == albumName).Get().FirstOrDefault();

if (album != null)

return album.Images().Where(x => x.Status == ContentLifecycleStatus.Live && x.Visible).OrderBy(x => x.Ordinal).ToList();

else

return new List<Telerik.Sitefinity.Libraries.Model.Image>();

Make sure to add this using statement:

using Telerik.Sitefinity.Modules.Libraries;

This should get you back in business.
