This morning’s task: Making the thumbnails in my blog compatible with IBM WebExplorer 1.0 on OS/2 Warp 3. 🤪

Before:

After:

And the fix was using -define jpeg:sampling-factor=2x1 when creating the thumbnails using ImageMagick.

I’m not really sure, though, what’s going on. 🤔

(I tend to post all that retrocomputing stuff on Mastodon lately. 🤔)

@movq@www.uninformativ.de That is super weird 🤔 I don’t get what’s going on either? 🤔

Then I realized there’s more than one version of “BMP”

🤣

@prologic@twtxt.net Maybe one day I’ll have the motivation to learn enough about JPEG, so I can understand the reason behind this. But not today. 😅
