Seriously "NASA's New Eye on the Sun Delivers Stunning First Images" is the kind of press flack hucksterism we'd decry if any other firm promoted itself that transparently.
To get this thing to work, they had to overcome a lot of technical obstacles, including thermal stability of the focal plane and optics (it's a high-resolution telescope that mostly sits in the sun, but goes into Earth's shadow regularly, altering lengths of optical paths), and bandwidth issues (a set of 16-bit 4096x4096 images every ~10 seconds).
Finally, and this is not made clear in the press materials, they're exploiting some neat spectral effects to get unusual "images": spatially-resolved velocity (thru Doppler shifting of spectral lines) and spatially-resolved magnetic field (thru the Zeeman effect). That is, an image of local magnetic field. Those calibrated images are a main driver of the science -- although the flare pictures are cool.
Putting it all together is an impressive technical feat.
NASA already has your money, and now they are trying to demonstrate a little ROI. So pipe down and be amazed :-)
