-This is debatable, but frequency is low (it only occurs once on this site. If you are writing up all missing image alt text as a group, you might increase your estimate of frequency, but this site doesn't appear to have a lot of undescribed images); impact is low (it is possible to determine the purpose of this image by either clicking on it to see what it links to, or inferring some things from the external link and image file name (both unpleasant alternatives for a screen reader user); and persistence is high (it's not going to go away).
