This morning I tried looking at my blog through one of the computers at work. The pictures looked fine. Later on in the day I had a co-worker look at my blog through his laptop. Again, everything looked fine.
So the issue is apparently confined to my laptop.
Just f'n lovely.
I figured when I got home from work I would try a couple things, and if they didn't work, just let it be. If everything looks good everywhere else I could live with the graininess.
It actually kind of reminds me of when I used to play club gigs. Quite often the sound we heard on stage was atrocious, but as long as our audience had good sound, all was well.
The first thing I tried was to look at my blog through a different browser.
Annoying, annoying, annoying.
But at least I get the "good sound" now as well.
