Instead of dealing with an extra step like zipping because it seems to be causing some confusion, just upload regular files.
If you have 50 files, and you intend to organize them in different albums, I suggest you put them into separate folders to reflect that structure. It will make it a lot easier to add the photos to your coppermine albums since the folders reflect the albums and you select the album you want to upload the file to. It's hard to explain. But if you put them all in one folder, you will later have to manually check/uncheck the files you want to put into their respective albums.
If you do not have an FTP client, you can simply use Internet Explorer. Enter this in the address bar:
ftp://yourusername@yourdomain.comEnter in your cpanel login when requested.
Navigate to public_html/gallery/albums
Drag and drop the folders/files from your computer into the albums folder.
In coppermine, as admin, click batch upload.
The manual should explain it better from this point since it has pictures.
