Anyone knows an app to rename 5000 images?

[abispac]

Heres the deal , i have a collection of more then 5000 mp3 albums, most of them with covers, some are named folder.jpg some cover.jpg, some have the name of the album,not to mention i have lots of coversmall.jpg and thumb.jpg, what i need to do, its to rename the larger image to cover.jpg to use with Freebox or etouch, i can delete most of the thumb,coversmall images so they dont bother the larger images. I found jukebox cover manager, but it only has an option to batch rename albums with only one image, it dosn seem to work on albums that have more the one image, thanks for any help provided.

You can delete all thumb.jpg and coversmall.jpg from a command prompt.
Go to the root directory of your music and type the following:

del thumb.jpg /s
del coversmall.jpg /s

You can also use JCM to do the same in two steps by setting thumb.jpg and coversmall.jpg as the name of the Thumbnail name in the settings and then use the Delete Thumbnail option.

If there is more than one image in a folder, how will you know which one to rename?  You could check the size of the image, but that is not always correct.

Media monkey might be useful.  I used it to restructure the folder system of my music collection.
Not sure what it can do with album art in big batches.
It's free.  www.mediamonkey.com

I've used this before to clean up some screenshots taken for NES snaps in MaLa.

A simple batch file with windows commands might work for your case.  If you can get it down to one picture per folder you want to keep (i.e. delete remaining pictures- or maybe just move them to a temp folder to review later?), then you could write a batch file to look in each folder and rename *.jpg to (whatever you want).jpg
