OK... must be doing something wrong... dang if I know what it is.
Previously loaded videos to CPG... name of vietlaotrip.mpg. Decided later that I wanted a custom thumb. Created an image named vietlaotrip.png and uploaded to same directory as the movie.
Next, used batch add and added the png file. As noted in the docs I ended up with a thumb_vietlaotrip.png and it does replace the stock image for the movie.
However, now the album also contains the original png image as well, not what I had intended. Where have I run amock?
Thank you.
Use that (http://forum.coppermine-gallery.net/index.php/topic,60272.0.html) plugin.
Thank you... tried it before I wrote, then realized that I needed write permissions.
