By default, when Orchard displays a content item such as a blog post in a list, it uses a very basic summary template that removes all markup and then extracts
the first 200 characters. Removing
the markup has
the unfortunate effect of removing all styles and images, in particular
the image I like to add to
the beginning of my posts. Fortunately, overriding templates in Orchard is a piece of cake. Here is
the Common.Body.Summary.cshtml file that I drop into
the Views/Parts folder of pretty much all Orchard themes I build: @{
Orchard.ContentManagement.ContentItem contentItem =
Model.ContentPart.ContentItem;
var bodyHtml = Model.Html.ToString();
var more = bodyHtml.IndexOf("<!--more-->");
if (more != -1) {
bodyHtml = bodyHtml.Substring(0, more);
}
else {
var firstP = bodyHtml.IndexOf("<p>");
var firstSlashP = bodyHtml.IndexOf("</p>");
if (firstP >=0 && firstSlashP > firstP) {
bodyHtml = bodyHtml.Substring(firstP, firstSlashP + 4 - firstP);
}
}
var body = new HtmlString(bodyHtml);
}
<p>@body</p>
<p>@Html.ItemDisplayLink(T("Read more...").ToString(), contentItem)</p>

This template does not remove any tags, but instead looks for an HTML comment delimiting
the end of
the post’s intro:
<!--more-->
This is
the same convention that is being used in WordPress, and it’s easy to add from
the source view in TinyMCE or Live Writer.
If such a comment is not found,
the template will extract
the first paragraph (delimited by <p> and </p> tags) as
the summary.
And if it finds neither, it will use
the whole post.
The template also adds a localizable link to
the full post.
