Anyone else have to fight past pangs of guilt when posting an image over 400 pixels wide?

Every time I have to remind myself it's not 1999 and I am not destroying connections of other fans. It's an fandom old habit that I can't quite shake. Meanwhile everyone else posts huge images with no collateral damage. I have to fight myself every time to post as big as 800 pixels.

Anyone else have any fandom old habits that are out of date? Or is this a 'just me' thing?
