Is it me, or do I get huge quality loss when I upload an image to Warcraft Realms.

Take for example this image:
http://www.warcraftrealms.com/user_image.php?id=571

Its ok quality. Not to bad, but not omfgroflwtfpwnbbq good neigher.


Now lets take a look to that same image, uploaded with Image shack: http://img399.imageshack.us/img399/3989 ... pvptj4.jpg

Looks like normal JPEG 75 compression to me. I bet rollie drags your images through some of the GDlib functions.

Yeah, it's a default 75 compression. I'm looking at decreasing the compression.

I went ahead and increased it from 75 quality to 95. Should make the images better.

do I need to reupload or not?

It won't reupdate if that is what you are asking. So yes, if you want to have a higher quality version, you'll have to reupload.

My self I would go for PNG files if space ain't the issue. Otherwise jpeg 75 - 100 is just fine :).

I've always been unhappy with ImageMagick's JPEG compression. Images are usually littered with artifacts unless you bump the quality over 90, and then the files start getting big. Guess I was spoiled by Photoshop, which always seems to create higher quality at smaller file sizes.

the problem is that jpeg is a compression and the noobs at imageshack "compress" it again..well if you're in informatics you know that this is b$ and nonsense :-/

actually is the other way around
The Imageshack pic is just as good as on my hard drive, only the pic linked above from warcraft realms is (was) worse ;)
