Edit photo title for all pics

Hi,

I successfully imported the mysql backup file and the g2data dir on a new server. My question is ..

Is there some sort of a script or recursive sql command that I could use to change all titles that begin with "IMG_**" to a blank. I would rather have a blank title for these photos than to have the filename. I did not choose the option to set the title to filename during the upgrade, but it still has the filename for most of them, except the ones that I have a meaningful title.

Thanks
Parker
