Hello,

In RSS Feed managers, I add a new feed but in template box just have something: title, description, link, id, date,...

Now, I need add image into feed, example:

Code:

[img]{feed:img}[/img]

My feed create on Joomla!1.5 Platform like this

Code:

<item>

                        <title>Etiam a viverra tellus sed at bibendum nibh</title>

                        <link>http://mywebsite.com/link-to-acticle.html</link>

                        <guid>http://mywebsite.com/link-to-acticle.html</guid>

                        <description><![CDATA[<p><em><img title="Title of image" src="http://mywebsite.com/link-to-image.jpg" alt="Title of image" width="130" height="55" />Phasellus quis augue odio.
