I've created a presentation as a series of .png images, one per slide. What is a good way to convert these into a .ppt (PowerPoint) that I can give to some audio-visual person? I'm entirely on Linux, with no Windows or Mac software available.

(Or maybe PowerPoint isn't the only game in town for presentation file formats?)

I'd output to PDF, which is commonly used for presentations. To convert use the convert program (from Image Magick).

convert *.png presentation.pdf

If you don't have convert yet, install the imagemagick package

sudo apt-get install imagemagick

(It looks like you can also use convert directly to a .ppt file, but for me this doesn't work as well.)

You can use OpenOffice.org Impress to import each of these PNGs into single slide, apply the desired transitions and export to a .ppt file.

OpenOffice.org comes with most Linux distros

Rather than try to directly convert the PNG files to a PDF or other format presentation, create a new presentation in Inkscape with the PNGs imported. Inkscape with Inkscape Slides turns out to be a great way to make presentations, and a good way to deal with old presentations that exist only as PNGs. (See question Converting Inkscape layers directly to a slideshow presentation?)

However, the other answer recommending ImageMagick convert is useful too.

You can create a Markdown file with all the slides, and then use Pandoc to convert it to a PowerPoint file. Here's example Markdown:

And here's the command to convert it to a PowerPoint file:

pandoc slides.md -o slides.pptx

Good news! There's a way to do this using LibreOffice Impress!

Open a new slideshow with LibreOffice Impress, then click Insert, Media, Photo Album. This dialog will appear:

Dialog

Click "Add" to add the photos you want to add, and then click "Insert Slides" when you are doing. LibreOffice will create a slide for each image. Save it as "filename.pptx" (PowerPoint's format) when you are done, if you need a PowerPoint file.

I recommend LibreOffice over OpenOffice by the way, as the former is much better maintained than the latter.

I don't remember if this is the exact solution I used, but I have run some kind of add-on to OpenOffice that just took a whole directory full of images and created individual slides from them. It was absolute magic. Give this a try, I hope it's the one I'm thinking of http://ooomacros.org/user.php#95976
