I have a rich text field, richtext that contains text and an image html image tagged fragment such as the following:

Spectacular Mountain etc etc
<img src="pic_mountain.jpg" alt="Mountain View" style="width:304px;height:228px; />

I wanted to create a Computed for Display field that returns just the image fragment. I found the following code would work:

import re
pat = '<img .+ />'
match = re.search (pat, richtext)
return match

at a standalone python session. But if I used the code in plomino, the import re instruction is not allowed. Any suggestion how I can do this?
