For the current J3 and former series, the users haven´t had a "better practice" guide, to help them act in their own best interest when populating their media folder(s).

This feature request is based upon once again seeing a site with a gigantic amount of media files in the root of the /images folder. This last case of volunteer work showed approximately 1400 images in the root of /images, which means it takes ages to load and eat up system resources. Yes, they should have used fewer images and made use of strategic use of subfolders, but they didn´t and didn´t know it would be smarter.

Suggestion: Set a default folder size of the /images folder and each of its subfolders, to help users do a better practice. The default could be set at installation based on the optimal settings and system resources available at the users web hosting.
At each upload of a new image, a check would then be in place to verify that ex. countSize of folder was within limits, or else it would suggest user create a new subfolder in order to keep the fastest and best user experience when adding images to their site.

Without such a limit people tend to use a practice that is not in their own best interest. We could help them, and thereby us in ensuring the image handling always stays fast and easy to deal with.
