I like the PDF method you used because it did not take a whole lot of time downloading. Of course, you only had three photos, so I wonder how it would be if you had more than fifty. Nice photos, by the way.
I used PowerPoint when I did the slideshow on the antiwar protest in DC because I wanted to include a narrative with the photos. But that, I learned, wasn't the perfect solution because it took a while to download and not everybody was able to view it for whatever reason.
So this time, I used Irfanview, which is free software and not a bad thing to download because it has other functions as well. A lot of photographers at www.photo.net recommend it, and many of them are longtime pros who do nothing else but photography. You can download it for free here.

And if they give you the option to write captions, you have to write the caption on the photo which defeats the whole purpose of showing your photos.
So what I finally did was create my captions in PS using the canvas function. This is the first time I tried that method but I like it because I am able to control the size of the caption box.
But I notice the Irfanview method, which basically creates an "exe" file, also takes a while to download. And it might not be accessible to some people who view it at work, like was the case with the antiwar protest.
I guess the ideal method would be to use Macromedia Flash like the newspapers and news websites use. I have also acquired Macromedia Flash, but it is very complicated to learn and lately, all I've been doing is learning new computer software (self-teaching), and I've come to the conclusion that computer programmers are the worst writers in the world. It is impossible for them to explain the simplest method of doing things. And they always leave out steps, which force me to spend several hours figuring out how to cross that barrier on my own.
Anyway, now that I discovered I can make captions with the canvas PS method, I'm going to give the PDF method a try.
