Is there any way to show clickable video thumbnails? User then click on it, and the player opens at the deafult size...

Sorry but this is not possible with AllVideos.

Not directly, as already suggested. But there are a couple of work arounds. Let's take one video as an example. Create an article for your video and give it the same name as the video. Place the code for your video in your article "My Video". So you might have:

{flv}myvideo|640|360|1{/flv}.

Notice that I have this video set to start as soon as it is called. You will not want to do that if you put more than one video in an article. Make a screen capture of a video you want to display and size them appropriately. Maybe 100 x 125 or a little smaller. Use another article as your video gallery. Let's name it "Video Gallery". Place the thumbnail(s) in your new article "Video Gallery". Using "myvideo" as the example, add a link to "myvideo" thumbnail.

Now when you are viewing the article "Video Gallery" and you click on the thumbnail "myvideo" your article "Video Gallery" opens and "myvideo.flv" plays.

So basically, you have article to hold thumbnails for your videos in a "gallery" format. You may even want to categorize your videos and have one article for each category. Then you need one article for each video to play.

Actually, I just thought of another way - maybe someone on the forum already knows how to do this.

When you specify the URL in a link, you can also specify parameters. In this case, you could do this with two articles. You might have a number of thumbnails on a page and a second article with your player. Clicking on a thumbnail opens the page with your player and the parameters in the URL transfer the video to play.

Someone who is really good with url and associated parameters may be able to chime in on this one. I think it may also be possible to have the player on the same page as the thumbnails with a go to location on the page. Again, anyone out there who knows how to pass parameters in a URL?
