This function does not accept regular expressions. Use php.net manual for accepted function parameters.

preg_match() is used for regular expression matching.

Are you looking for that exact string (as in, checking if it's there)? Are you wanting to search for img tags in general? img tags with path but any filename? Any path, exact file name? img tags with any file name of .gif extension?  Need more info.
