NiHaoMike:
Wouldn't it be trivial to add a bit of logic to check if the thumbnail is a bigger file, in which case make the thumbnail a symbolic link to the original image?

I've noticed some people wasting space by saving schematics in 32-bit colour depth, at a much higher resolution than necessary. I keep my schematics small by using <8-bit colour depth (often 1-bit) no transparency and a fairly low resolution. Most of my attachments are under 10kB.

Good policy. I try to keep the resolution of my drawings, photos and screen captures less than VGA (640x480). When they're "big", HD (1280X720), tops. The size of their files range from 30kB to 500KB. My drawings use no transparency. But it hasn't crossed my mind that when they're monochrome I could convert the picture to B&W and save space. I'll use this expedient whenever possible from now on.

Your 771.27 KB image doesn't matter that much but in the past we've had 40MB+ of self-opening images in just one post.

I didn't know that, the thumbnails for my 9.5kB 800x480 16 colour .gifs are only 2.5kB.


--- Quote from: NiHaoMike on July 01, 2019, 01:02:14 pm ---Increase the thumbnail size to something like 640x480 or 800x600.

LOL

Here are two examples of what gets my goat!  (Sorry to the users I pulled these examples from.)
Take a moment to crop.

I also have a CSS style to limit the photo height to my screen size.

Just use Gimp to reduce the image to indexed, with a maximum palette of 256 colours and export to PNG. PNG supports 1-bit, 2-bit, 4-bit and 8-bit indexed modes and Gimp will automatically select the correct one, so if it has two colours, you'll get a 1-bit PNG.
