Within the past day, I've noticed that any new photos I upload (specifically digital graphics) have now started to appear blurry or "fuzzy". I am using PNG files that I resize to the exact size I want, but no matter what I try, they now are blurry.
A good example is this page: http://www.squishycutedesigns.com/little-stitchy-embroidery-contest/
You can see how blurry the header looks when compared to our website's header, for example. (I uploaded this image just today).
One other example can be found here: http://www.squishycutedesigns.com/free-printable-embroidery-patterns-jennifer-smith/
The header (Little Stitchy Collection) and the "Artist Spotlight" image further down are both very clear, and these are images I uploaded a day or two ago. But today I uploaded the long narrow image in between (Enter our contest) and you can see the difference in how blurry it is.
I've driven myself crazy trying to figure out what I'm doing wrong all of a sudden, but I really don't know. I've done nothing different in how I create my images and upload them. And I've tried deleting and re-uploading images many time, with no luck. Any advice would be SO appreciated!!
Thank you in advance!!
