Should fix issue #33, although the regex is sketch.
Open to suggestions to improve this (Y)
Sorry, I left the link of the regex in this comment thread and not the code. I'll put it in the code in the future.

If I wanted to check whether the imgElement.src is a absolute URL, is there an alternative to using a regex?
