Can Coppermine handle a few big video files? I'm just curious and I need a good gallery, that can handle a lot of multimedia, from big video to regular images.
Coppermine can handle all file types. You should probably focus on finding a webhost that will meet your needs, because Coppermine certainly can do everything you want.
as kegobeer suggested: coppermine is capable of displaying videos in all sizes. However, http upload isn't (related to browser and server issues, not to coppermine issues), so you'll have to upload large files using FTP and then batch-add (that's even the recommended method when using coppermine). However, coppermine doesn't stream videos, but displays the videos with the video player the visitor has installed on his pc embedded into html pages. As a result, you will have to take care that you're using video formats that the target audience of your site will be able to play. Real streaming of video files requires special server setup that usually doesn't come with "regular" webhosting accounts, so that's not something coppermine does. In fact, coppermine doesn't touch the video files at all - they are stored on the server and coppermine just provides the surrounding html.
