Justin,
I did what you said, just uploaded the file and downloaded it again, and
the weirdest thing is happening. When I Form-Upload/FTP-Download it, I can
see it on my local computer, it opens everywhere. Now, when I try to see it
from the web site it is uploaded (http://wwwwebsite/file.jpg), it does not
display. mmm Any suggestions?
