Hello,
I need to optimize my images but i can’t find a good plugin for the job. I mainly use PNG pictures on my site.
I’ve checked out the ‘Pagespeed’ topic on the forums but people recommend ‘EWWW Image Optimizer’, but unfortunately i can’t use this plugin because i get the error:
EWWW Image Optimizer requires exec(). Your system administrator has disabled this function.
Are there anymore plugins i can use that don’t affect this theme?
Many thanks 🙂
I recommend simply setting the quality level to “60” by adding directive to your functions.php file, then do regenerate images plugin. Bam! Some people like “smushit” also.
Anyway…. it may not work with png format, hadn’t tried that; but this does work for jpeg images really well.
add_filter( 'jpeg_quality', create_function( '', 'return 60;' ) );
I have not tried this:

@neotrope Many thanks Christopher, Would you recommend changing my format from PNG to JPEG?
Also. thanks for the ‘Compress PNG for WP’ plugin, will check that out 🙂
Well, typically jpeg is used for photos, png is used for logos, charts, illustrations, because it’s color reduced; so a compressed PNG might only have 256 colors, while a jpeg can have 16,000 when compressed (that is not exact, just an example). PNG is a modern version of GIF, not a replacement for JPEG 🙂
