This has been niggling at me for ages now. If you look at my avatar it appears very blurry whilst if you look at it via my members card it's sharper and size correctly. any reasons why avatars are resizing and looking blurry in the postbit?
I'm assuming it's a re-sizing issue though I've tried 100px square (the size it's being re-sized to) and still it's blurry.
I am sure i tried 96px by 96px and measured the avatar box which is set at 100pixel square but still some kind of re-sizing is occurring. I'm wondering if it's something to do with the member card size at 200px and it's blowing it up to this size causing the low quality in the images by re-sizing in the postbit. I'll try 96px square in a second but I'm 100% sure i tried these sizes and it didn't help.
I didn't see the original avatar for comparison, but as Brogan said, it's can be the nature of resampling. Even cutting out just a few pixels can take something sharp and destroy it (take a 16x16 image down to 12x12 as an example).
