PHP preg_replace img that contains specific string inside src element

Question

I want to replace any html image tag that contains a specific string inside the "src" attribute.

Example:

<img id="IMG1" src="cid:[email protected]"/>

Should be replaced with "SOME STRING".

Images that contain a valid URL must not be replaced:

<img id="IMG1" src="http://someurl/image.png"/>

Can someone help me getting the correct regular expression for that?

EDIT: This one is my basic example but it replaces every image tag. I tried to get it on my own but unfortunately it didn't work:

preg_replace("/<img[^>]+\>/i", "SOME STRING", $myBaseString)

Thanks a lot.
