Why small images? Don’t send a 1.4mb png when a 30kb jpg will do. Image optimisation is nothing new. As many of my other developers who touch frontend code know, don’t send huge images to the browser it will slow down page speed. Same applies to the messages you send you colleges. The last half year, while working from home, more of my communication has been digital than ever before. I knew about image optimisation before, even contributed to an image service lambda at work.
