I tried like below

The . stays for any character, as such your regular expression seems
to be way too greedy.
This however should not harm too much if there is only one img tag in
one line, although backtracking
might be a performance issue. I do however fail to understand the
behavior you described.
Anyway, I believe the following regex should do fine:

item.description.gsub! /<img.*?>/, ""

How did you do with the >10 replies you got before? Did Hpricot work out?
