Yes - your posts are fine!!
I use Firefox too at home, but in the office I use Internet Explorer. I just noticed that the frame around my last picture shows up in blue here at home, but when I used to use IE it was ALWAYS gray. I am now curious if I have inadvertently changed something (and I like it better this way) or if it's just my browser. I was specifically noticing the frame around the last picture!
Gosh, how curious!
The frame around Mansions of The Lord is gray on my 'puter, and I am in Mozilla right now!
I'm stumped, LOL! I hope you get it figured out. These browser mysteries are always fascinating to me.
