Daiv Mowbray gave a pretty good answer to this, much thanks! BUT I have an additional question.
My question is this...if I limit to 10 items it only pulls the 1st 10 items in the alphabetized rss feed, so when I add Daiv's code it puts those first 10 in random order. I was hoping for a random sample of items "A-Z" not just mix up a1, a2, a3 and so forth and THEN limit what is displayed to 10 (actually 5). Follow my thinking?
My website is SCAutosTX.com and I've put the Image Feed Widget on the bottom of the primary sidebar. Right now it has no limits on it.
I'm so new to PHP, so I'm guessing there is an easy fix.
