I think a suitable resize will achieve the same, those normally will save with a moderate compression ratio.  If we were to resize images to, say, 1200 pixels (largest dimension), it would reduce the data size and also speed up loading of photos.

(Testing image attachment with this post ...)

1. That sample is about 500kB in size. Some people are still on 100MB/month data plans.
2. Even if data isn't an issue, people still have to physically scroll vertically through a series of images.
(3. Don't get me started on people who then reflexively quote the entire post, requiring readers to do a repeat scroll through the entire picture set, just to add a "thank you" or to comment on one of the series.)

One can ask people to be more considerate of other peoples' budgets, time, fingers, etc. but it's usually an exercise in futility and it's never as effective as automatically generating thumbnails.
