Nowadays, photos from smartphones often weigh several Megabytes. My iPhone 11 pro gives standard 3,6 Mo pics and 4032x3034 pixels

In Invision, we can set the maximum weight of each photo, the space allocated to each, it's very good
We can also set the default display dimension in forums. Generally, between 800 and 1600 pixels. Rarely in the very large native dimensions of photos produced today.

This raises a question. Why keep original photos whose size and weight are not suitable for web publication?
Wouldn't it be appropriate to automatically reduce the size of downloaded images, so as not to use unnecessary space and to maximize their loading speed?

Of course, this device could be configurable, disengageable, with a quality setting ....

Original images are kept as you can change the sizes of the items you display. These are then created from the original asset
