>Once again, a web search will answer your question. I'd start here http://webp.codeplex.com/

Your reference is useful, I even identified your response as "Help", but, "Once again", the way you wrote it is intimidating, insulting and when reading it, it'd make/invite people to think to go away.

Yes, we know there is Google out there. I even spent some time searching for references and found some before posting the message. So, again, I did the search. I am not obligated to search on Google every time I need to post something on this site, but I did it this time.

Seriously, can I post a question on my own site with hopes to start an interesting conversation and collect input from others? Recently, someone replied to you with a very highly technical details about why we post here. I thought we had seen the end of it.

When I read posts like that, it makes me rethink about all the hard work we did over the years to build this interesting site/network, and by "we", that includes also you BTW as you contributed to it in various ways over the year and we all thank you for that. But, this way of posting is not inviting.
