Quality .jpg The compression for the .jpg image (0..100).
100 has best picture quality but image file size is the biggest.
Usually, a quality of 60 gives good results (enough compression to make the file size small but not too much so that the image still looks good)
Quality .png The compression for the .png image (0..9).
0 has best picture quality (no compression) but image file size is the biggest.
Usually, 3 to 5 give satisfying results

Warning the PHP GD extension php_gd2 is required for the creation of image thumbnails. Make sure this extension is available on your service provider's server. The module will detect this automatically.
