JPG File Size Optimization - PHP, ImageMagick, & Google's Page Speed
- by Sonny
I have photo gallery code that does image re-sizing and thumbnail creation. I use ImageMagick to do this. I ran a gallery page through Google's Page Speed tool and it revealed that the re-sized images and thumbnails both have about an extra 10KB of data (JPEG files specifically).
What can I add to my scripts to optimize the file size?
ADDITIONAL INFORMATION
I am using the imagick::FILTER_LANCZOS filter with a blur setting of 0.9 when calling the resizeImage() function. JPEGs have a quality setting of 80.
