The test to prevent JPEGs on OWS with low quality from being 'optimized' to higher quality (if the quality setting in WAM policy is higher than in the file on OWS) is not working.
image optimization can make the file significantly bigger.
AAM image optimization enabled and the JPEG quality in AAM policy is higher than the JPEGs on OWS.
Add the line below to /service/wamd/settings (create the file if it does not exist): export WAMD_OPT_IMAGES_NO_BIGGER=all Note this will return the original file if the 'optimized' one comes out bigger: subtly different behavior than making any other requested changes but leaving the quality the same as the file on OWS.
The test to prevent low quality JPEGs from optimizing to higher quality (becoming larger) is fixed.
