At a loss - EasySmilies

Possibly this is an issue with my host, but really not sure.  I feel like it might be something else.

On my forums, I have had EasySmilies installed for some time now.  I had set up a bunch of smilies and they have all worked just fine. Until recently....now I have maybe 7 or 8 smilies that don't show up on the list above the quicktext box and if you do click on them or type it in, you don't get the image to come up in the forums.

I checked the files and downloaded them to my computer and the image shows up just fine. I deleted one and uploaded it again just to test it and I got the same issues.  Anyone have any idea as to what would cause this all of a sudden?

Thanks.
