I changed All Assets view for Images library in SharePoint 2013:

 SPList imageList = web.Lists["Images"]; var view = imageList.Views["All Assets"]; view.ViewFields.DeleteAll(); view.ViewFields.Add("ThumbnailOnForm"); view.ViewFields.Add("LinkFilename"); view.ViewFields.Add("Width"); view.ViewFields.Add("Height"); view.ViewFields.Add("Modified"); view.ViewFields.Add("Editor"); view.Query = @"<OrderBy><FieldRef Name='Modified' Ascending='False' /></OrderBy>"; view.DefaultView = true; view.Update(); imageList.Update()

but, when I upload images, then the Thumbnail displays blank image. Only when I add "PreviewOnForm" field to view, then Thumbnail displayed correctly.

How can I display Thumbnail using ThumbnailOnForm column?

I set view xml with PreviewOnForm column, and now it works:

var viewXML = @"<View Type='HTML' DisplayName='All Assets' ContentTypeID='0x' ImageUrl='/_layouts/15/images/dlicon.png?rev=23'> <Query><OrderBy><FieldRef Name='Modified' Ascending='False' /></OrderBy></Query> <ViewFields> <FieldRef Name='ThumbnailOnForm' /> <FieldRef Name='LinkFilename' /> <FieldRef Name='ImageWidth' /> <FieldRef Name='ImageHeight' /> <FieldRef Name='Modified' /> <FieldRef Name='Editor' /> <FieldRef Name='PreviewOnForm' Explicit='TRUE' /> </ViewFields> <RowLimit Paged='TRUE'>20</RowLimit> <XslLink>main.xsl</XslLink> <Toolbar Type='Standard'/> <JSLink>clienttemplates.js</JSLink> <Aggregations Value='Off' /> </View>"; SPList imageList = web.Lists["Images"]; SPView view = imageList.Views["All Assets"]; view.SetViewXml(viewXML); view.Update(); imageList.Update();
