#24 allow setting the JPEG quality for resized uploads
When uploading images in different size than original, the image is decompressed, resized and re-compressed again as JPEG. The compression quality is apparently set to some low-ish value, which saves on upload bandwidth but at the same time creates ugly compression artifacts around high contrast areas of the image. That's not always the desired optimization.
If you would like to see some samples, take a look at my photostream, for example at this picture: http://www.flickr.com/photos/thinkfat/3150290073/
Hi,
I've deleted the image in the photostream and then realized that the link is now stale. But there are other examples in the stream.
But I also downloaded the sources of the latest release and hacked flickrcomm.cpp to use "95" as quality for JPEG images instead of the default. It's just one additional parameter to the QImage::save() method.
