Remove pasted image in posts.

[ils]

I have a forum that has a post structure like the following.

[subject]
[blah forum name blah]
[posted on date user name]

OFFENDING IMAGE (spacer.gif)

[body]
[body]
[body]
[more body]
[etc]

I'm trying to get rid of the image, as it doesn't show on browsers, but we just got Forum Runner and it shows a huge grey box in its place.

Since it was pasted in, it doesn't count as an attachment.
759 match(es) inside table post
41 match(es) inside table postparsed
759 match(es) inside table searchcore_text
179 match(es) inside table thread

My version is vbulletin4.1.10p2

I was thinking of running a SQL query from the adminCP to get rid of it, but I'm not sure which column to put in place of 'value'.
UPDATE * SET value REPLACE(value, ‘spacer.gif’, ‘’);

Am I even on the right track?
