Although I have never had any issues with the uploaded image quality of Boonex Dolphin maybe you do, or maybe you want to reduce the image quality or attempt to improve it. If image quality is good to begin with, I really don't notice any image quality loss. I am not a big image quality freak though, maybe you are and you might play around with this one.
I was recently reading a small blog post about improving image quality.
The blog states that you can apply the following suggestion:
The quality of the output JPEG files can be adjusted in inc/images.inc.php, where you need to replace the following line:
$writeResult = imagejpeg( $dst_im, $dstFilename );
with this one
$writeResult = imagejpeg( $dst_im, $dstFilename, quality_in_percent );
where quality_in_percent is a number from 0 to 100
So if anyone is interested in playing around with the image quality this is certainly a quick and easy modification.
Consider backing up the original file first if your not sure about this.
