The shortest version of a possible pattern would be /<img[^>]*>/.
This will probably work most of the time. A bit better would be this: /<\simg[^>]*>/. It will work with < img ......>, too.
You can insert very many corner cases to improve the pattern, but the better solution would be not to use a regex in the first place.
Instead, you should be parsing the html by dedicated parsers: How do you parse and process HTML/XML in PHP?
