Resize size issue

if somebody have similar problem, you can fix it by removing the 100 from this code in includes/classes/class.upload.php

// Creates the image
switch($extension) {
case 'gif':
imagegif($process, $destination);
break;
case 'png':
imagepng($process, $destination);
break;
case 'jpg':
imagejpeg($process, $destination, 100);
break;
 
Removing the 100 set the image quality to 60%, you should replace the 100% to arround 80% their should not be any major size changement and the quality will be much better than 60%
 
Hm.. I should read the compression level of the source image.
 
bad news, PHP can't tell the image compression level =(

Why should you need to compression level? I mean, almost every picture is compressed between 60-80% I had a class in school about the compression of pictures, especially jpeg. Their is no point of having a picture compressed higher to 80%, except if you wan to use more place on your server. The only reason you want to compress a jpeg to a level higher to 80% is when you are a professional photographer and you are showing your work on your website, otherwise, 80% is the best ratio for quality/size
 
I will like to know the compression quality to preserve this quality when the image get resized. Problem is that is huge the difference from a uploaded picture at 100% to 80%, but I think that you are right, there is no point in having 100% quality on something that was resized, and that have been improved by adding a sharpen filter.

BTW, the default level is 75% but I will use 80%
 
The default level of php is maybe 75% but most of the application used for images editing, such as photoshop or gimp set the default level to 60%

Having 80% compression level won't improve the quality of lets say 60% image, it'll just a wast of space.

It depends on what you upload, if you upload a image with quality less than 80% then yes, the thing is useless. But normally the images are on the range of 60->80%
