I'm new to SharePoint and SPMeta2. I would like to give this ImageField that I've created with SPMeta2 a default size of 300x300 since its always too big if you let people choose their own size.
public static FieldDefinition ContactPicture = new ImageFieldDefinition
{
Id = new Guid("ATD3DCAD-2A70-49AC-AFB7-BF4D2EDA5627"),
Title = "Kontaktfoto",
InternalName = "ContactPicture",
Required = false,
Hidden = false,
ShowInNewForm = true,
ShowInEditForm = true,
ShowInDisplayForm = true,
Group = GroupNames.ContentTypeGroupName,
};
