Without thinking too much, the solutions I came up with were two. The first one, to create a video with a product like Photo Story, upload it in YouTube or Google Video, and then embed it in my blog. This one I discarded because I wanted to have the article published fast, and didn´t want to go through any wait for approval period. The second solution was to embed a slideshow of some web album directly in my blog post.
So I created a Picassa Web Album with all my pictures, and copied the generated url for my album´s slideshow (click the slideshow button, and copy the url).
Then I tried embeding the slideshow in my blog post with an iframe html tag. Something like this:
<iframe src="[Picassa Slideshow URL]" ></iframe>
It is possible to tune the dimensions of the embedded frame with the width, and height attributes of the iframe tag.
It looks something like this:
Not bad, right?
