I need to remove image tags from text, so both versions of the tag:

<img src="" ... ></img>


<img src="" ... />

In C# you can use following code:

            string html = @"
<h1>
<img src="" ... >
</img>
<img></img>-bad
<img/>-bad
<img src="" ... />
</h1>";
            string result = Regex.Replace(html, @"<img\s[^>]*>(?:\s*?</img>)?", "", RegexOptions.IgnoreCase);

But be aware that modifying HTML with Regex isn't good approach, its better to use Html Agility Pack or other HTML parsers.
