It is impossible to write a blog post about HTML5 and embed slides in Flash in the same without suffering lots of wisecracking comments that don’t have anything to do with the content. To avoid this, I wrote Slideshare HTML and blogged in detail about how it works.
Well, I hacked and scraped and sooner or later this will always bite you in the bum. As it did when the Slideshare developers changed the URLs of the images of the mobile version which of course broke my embedding tool and got me a lot of emails asking me why oh why I have forsaken people.
Bitching on the developer mailing list of Slideshare helped and now the oEmbed API returns not only the number of slides and urls and all the other goodies but also the right image suffix to use.
So, in short words – it is fixed and as I am now using the API rather than building a ScrAPI it should work smoother.
