Image Sample Weirdness

I have "Show Image Samples" enabled, and most larger images get automatically scaled down, but for a lot of them, an image around 650x975 will be shown at "100% of it's original size", but an image around 1200x1500 won't be resized at all. Is this some random glitch that only happens to me?

I'm virtually certain that the "100% of original size" means that, while the image isn't actually resized, it has been been recompressed into a lower-quality JPG with a smaller filesize. I see this fairly often with PNGs and even high-quality JPGs.

Just an educated guess, but perhaps the image sampling isn't triggered by the dimensions of the image, but rather the filesize?

The percentage only reflects height/width scaling of the sample. Whether or not an image sample is created depends on filesize, dimensions, and file type. Whether or not images are resized is a separate user setting from "Show Image Samples".

Play around with searches like width:<700 height:<1000 filesize:>800kb -gif and see for yourself.

I know that, but sometimes a large image will be resized, and sometimes an image almost the exact size won't.

Comparable filesize and width/height? Any examples?

I'm looking for it. I didn't check the actual size, I meant width/height by that. I know it's some older images because more recent ones always work.

I said filesize, dimensions, and file type.

post #629290 (bigger dimensions, smaller filesize) has a sample; post #633347 does not. Apparently one of the cutoffs is between those two.

I had a list of old posts with large dimensions, filesize, and no sample but I deleted it apparently.

Well, I noticed that post #700125 gets resized, but it's child doesn't, and they have the exact width/height. Do only images of a certain filesize get resized, regardless of the width/height?

Again: filesize, dimensions, and file type.

width:>1500 height:>1400 filesize:<100kb -gif -flash

width:<800 height:<600 filesize:>800kb -gif -flash
