I find myself once again fighting with Keynote and LibreOffice's presentation mode, and wondering what's y'all's favorite HTML slides generator?

back at Big Nerd Ranch, we switched from our home-grown presentation software to DeckSet. Content via markdown, styling via another mechanism. Last I saw it doesn't do HTML slides, but if you're presenting off a Mac, it was quite usable.

Okay, dumb question: About half the JPGs and even PNGs I throw in show up as super tiny thumbnails, even when the jhead looks like:

File name    : images/service-pnp-fsa-8a17000-8a17200-8a17204v.jpg
File size    : 246737 bytes
File date    : 2026:04:01 15:03:01

Color/bw     : Black and white
JPEG Quality : 95

And no amount of ![1500%] or messing around with the density in ImageMagick or whatever seems to make it legible or large.

Even when I display that, grab a screen cap, and throw it back in. Other images are just fine.

If it's HTML output, it sounds like the <IMG> tag has thumbnail size attributes.

something with the image dpi?

Yeah, I've tried a bunch of -density options. A couple of suggestions over on the Fediverse that there's something about embedded thumbnails? I'm going to try both using exiftools to make sure that there's none of that, and giving a slight color wash, today, because that this is happening even after a screencap makes me wonder if there's something about B&W that's messing this up.

can you mail me a couple of misbehaving images? (markd@borkware.com)

Found it! Those two images, I didn't have a blank line before the image specifier.

It was a markdown issue, not an image issue at all. Sigh.

heh. the legacy of "tabs vs spaces in makefiles" continues to exist in other forms
