You can do this by using a
ListViewin virtual mode, and then adding your generated thumbnails to theLargeImageListduring theRetrieveVirtualItemevent (if they are not already there).If you wanted most of the work done for you, you could use a
FastObjectListViewfrom the ObjectListView project (an open source wrapper around .NET WinForms ListView) and then follow this recipe on how to use images loaded from a database. Your images, of course, would be thumbnails created from the source rather than images from a database but the logic is the same.
