It's possible, but not easily done, and begins to carry Plogger away from its conception as a "lightweight image gallery".
I would suggest instead using a free service like vimeo.com, which allows you to host and embed your videos in blog posts and webpages, as well as contains an online gallery.
Thanks but working with one of the video hosting companies is a thing that I don't want to do (for the same reasons that I use plogger instead of flickr ;) )
I'll try to find some video gallery program then :)
I don't know what kind of website you have, but if you're using WordPress (for which there will eventually be a Plogger plugin), there is someone who wrote a plugin for video inclusion, in posts or as a gallery. Also supports option to use services like vimeo.com to store your movies and still show them inside your own site.
There are several options over there, all still in development (as always): http://www.xyooj.com/blog/plink/technical/27/wordpress-youtube-video-gallery-plugin/
so you can see withs plugins are available and you can select withs you want to have and download / auto install in plogger
its just a idea
so you can make more scripts and plugins and the people who are looking for a light gallary scripts can leave the plugins for what the are so they don't have to install them ?
