Problems with updating resized pictures

[ophelia]

I wanna replace some pictures with new ones tagged.

I uploaded the picture I wanted on the album and with the same name of the old picture.

After that I went to Admin Tools > Update thumbs and/or resized photos

I had tried to update with both options:

Only resized pictures
Both thumbnails and resized pictures

And it didn't work. The full sized picture changes but the resized picture still shows up the old one.

Look: http://www.bethany-source.net/gallery/displayimage.php?album=5&pos=50

The resized picture shows the picture with the old tag.

The full sized pic is right, with the new tag: http://www.bethany-source.net/gallery/albums/Appearances/Coach%20Carter%20Los%20Angeles%20Premiere/coach50.jpg

My coppermine version is 1.4.6.

What am I suppose to do?

Thanks.

First update your gallery. Latest version is 1.4.16.
Then you should check file permissions and ownership of the intermediate image you want to recreate and of course permissions of the folder it's in.
