Unfortunately, 'origLinks' has already been computed in full, before the
'take 10' applies to it. Why? Because 'origLinks' is the result of an
I/O action, which forces it:
> main = do ...
> origLinks <- mapM (getLinksAfterImgByAttr ...) picLinks
What you really want to do is to trim the picLinks before you download
them. e.g.
> main = do ...
> origLinks <- mapM (getLinksAfterImgByAttr ...) (take 10 picLinks)
