I got this image just fine !!!
I use Firefox, but can't find any setting that would block your image tho .....
BUT, I no longer get the banner at the bottom of the Posts either, but I get the ones to the right !!!!
- I thought Mike caved in and eliminated the one at the bottom ????
I also noticed that the Optional Link URL and Optional Image URL boxes are "pre-populated" with http://
If I copy paste a full URL in those I will get the http:// twice and I delete one of them.
Only thing I can think of at moment, If you are getting it in there twice, my browser may be rejecting it ???
Anyway, I got the image.
