Yeah that's a valid point for sure. But I always edit quotes when needed (to reduce guff and make it more readable).
I found it curious people felt that way! I've always tried to take the extra effort to post nicely sized inline images whenever possible (in the belief I was providing the best usability for the reader) and kept the thumbnails for big stuff and/or multi-images.
Now it seems people prefer thumbnails? I find thumbnails really annoying when they are just a very simple schematic or something small, but you still can't see it until you have to open it. To my logic, something small could have just been included in the text and been better for everyone.
