It seems that WordPress compresses jPEG images after uploading, sometimes downgrading the quality as much as 60%. I went looking for ideas about how to achieve maximum image quality,
One possible answer I found on Graph Paper Press is to use their plug in, GPP Improve Image Quality. It promises a 60% to 100% improvement in display.
- Access the download page.
- Click on the Download button. Do not click on the Demonstration button, as that is not working.
- When you click download, the site will request your full name and email address. To receive the free download, you must agree to receive the monthly newsletter.
- Then check your email, click on the download link right away, as it will expire in one hour.
- This is where this easy fix breaks down: it is supposed to be a plugin for WordPress, but I think WordPress doesn’t have plugins. At this point, you need to upload the .php file into your wp-content/plugins/ folder, and then activate it from your Plugins page in WordPress.
It should be noted that improving your image display would mean slower display.
I am going to try to resolve the lack of plugin capability since this was designed for WordPress, and its simplicity is fare superior to any other solution I came across, and just my speed. Of course, imaginary solutions are generally far superior to actual solutions.
