Hi,
If you defined a media library, you do not need to set the
Path property in the MediaGallery webpart. To select appropriate media library, please use Media library* property.
To display image as requested (using vertical layout with description), you can use following transformation:
<%@ Register Src="~/CMSModules/MediaLibrary/Controls/LiveControls/MediaFilePreview.ascx" TagName="MediaFilePreview" TagPrefix="cc1" %>
<div class="MediaGalleryDetail">
<cc1:MediaFilePreview ID="filePreview" runat="server" Width="200" Height="200" maxsidesize="530" />
<br/>
<%# CMS.GlobalHelper.ResHelper.GetString(Convert.ToString(Eval("FileDescription", true))) %>
</div>
Please check
Display active content property to display images correctly.
Best regards,
Ivana Tomanickova
