Hello

So I'm not advocating removing the 'flash' button …

I do! Flash is a dead technique. More and more browsers remove the flash plugin or require a button click from the visitor to activate the plugin at least.

… but what I would like to know is what the 'flash' button was for though?

It was introduced, mainly to embed videos. At that time Flash was the common way to do this.

I mean if I click the 'flash' button on this site it asks for a flash url, without the YouTube hack what url are you meant to put in this box?

I thoght, I was verbose enough, when I showed the URLs for embedding, Youtube and Vimeo provided to me. I described the actual status how the video providers offers their way of embedding and what I think we have to do, to support it.

I just don't understand what the purpose of the 'flash' button was for?

See above.

Tschö, Auge
