Bad image quality? new!
by Richard, 13 years, 6 months ago
Hi there,

We currently use class.upload.php on our site, but I'm having problems with it when it comes to uploading the images. The quality of the image uploaded is really bad and I've tired to follow FAQs and the document as much as I can but can't seem to fix the quality and wondered if you could give me some advice. An example of the type of image I'm getting is here:

You can see the 'Interval' image is really awful, yet the original that I uploaded is a very high quality perfect .jpeg.

Cheers,

RichardReply

Resizing of text and logos is a hard thing to do anyway.

But you can first change the JPEG quality setting:
$foo->jpeg_quality = 95;

You can also unsharp your image, but it will not be better in all cases:
$foo->image_unsharp = true;;

This is a issue with downsizing big images to small thumbs. You can get it also on photoshop or any other graphic software.

As a photograper I can sugest you to downsize in small steps until you get the final image. Try 75%, 50%, 25% until the final image. Do not compress the steps... only compress the final image.Reply
