How Image compression works on C5 ?
How concrete5 compresses images ? Does it compress original image or only compress thumbnails that are generated from original image.
On my C5 18.104.22.168 installation, When I upload image with 3 MB, It generates 14 thumbnails. But when I download original image it have same size. It does not compress original image.
But it seems it compresses generated thumbnails.
What you describe sounds right.
In 22.214.171.124, there will be a new client side image resizing option. It allows for setting the max width, max height, and image compression quality of images before they are uploaded to the server.
This feature was added by community member mesuva.

I am assuming that the original local image will remain the same size.
