replace

I'm having a problem with some images I'm using on my WordPress blog. After a migration I renamed every image replacing spaces with underscores, so

HIDDEN_264_4062_FOTO_IDF los MID.jpg

was renamed to

HIDDEN_264_4062_FOTO_IDF_los_MID.jpg

But althought the trick was necessary and worked for most of the posts, some of them try to find the old image, with spaces:

This is not found

http://www.example.com/files/HIDDEN_264_4062_FOTO_IDF%20los%20MID.jpg

and this should be the right URL

http://www.example.com/files/HIDDEN_264_4062_FOTO_IDF_los_MID.jpg

Careful, though, 'cause the "%20" is only shown on the browser: the text on the database shows spaces, not "%20".

I'd like to know if maybe I could make a SQL query in my WordPress MySQL database that replaces spaces in .jpg files with underscores. The path of the images is always the same, so the rule should transform this:

/files/HIDDEN_264_4062_FOTO_IDF los MID.jpg

/files/HIDDEN_264_4062_FOTO_IDF_los_MID.jpg

the "/files/HIDDEN_264_" part is always the same, but the rest varies. Is some way to perform this? Maybe a rewrite rule on Apache (our current webserver)?
