This is intolerable, no true art site should allow lossy formats like JPEG or GIF, even PNG and TIFF has a subtle degradation of the Artwork, most people with basic equipment won’t notice, but true graphic designers know how to make the difference, hence the necessity to only allow RAW files for photography, and BMP, PSD or SGI formats for 2-D art should be allowed. I also think the creator should provide a calibration file to help us understand the true message and philosophy from their art, the same way FLAC or MP3, or CD audio’s wav will never equal the sound of a vinyl record playing on Cabasse speakers and a McIntosh amplifier.
My eyes hurts, every time I notice artifacts and gradients on what should be a beautiful flank that should inspire perfection, these lossy formats ruins the true experience of getting close to our waifus. As a photographer myself, the only source of noise that should remain is the Cosmic microwave background, we should be able to feel it as a part of the subject, which makes Art a part of something much bigger.
