Progressive jpgs

[LDDG]

Can IPS be setup so that all thumbnails it creates on uploaded jpg attachments be created as progressive jpgs? This would help inmensely with Google PageSpeed Insights and optimizations.

I did some research on ImageMagick, since that is what I have my IPS configuration use for it's imaging processing, and it seems that this command in Image Magick will take a jpg image and convert it to a progressive image:

convert -strip -interlace Plane -quality 80 input-file.jpg output-file.jpg

I guess if we can incorporate this code into IPS's ImageMagick function, we can create thumbnails as progressive images!

Anyone has any idea how to get this done?

Any developer wants to create a plugin for this? I’ll pay for it, that’s not a problem.

No developers want to take this on? Payment is not an issue. Just send me a PM.

I've installed nginx_pagespeed and both pagespeed insights and gtmetrix scores are awesome. It takes some trial an error though. I strongly suggest to install Lighthouse extension on google chrome, this tool will help you a lot to improve performance. 

With nginx_pagespeed you can also use the webp file format, which is lightweight and very fast. There's a lot of "filters" to use.

If you have access to your server configuration it's not difficult.
