Downloading issue!

[Emmanuel Opio]

Hi,
      Am studying at a University in E. Africa but the problem is that our
server administrators blocked "ftp" and filtered out images, so we can not
download any image file, the most common extension for operating systems.
  I was just requesting then if there is a HTTP site with zipped freeBSD
image files ready for download. It would really help a number of us out
here.
Thanks abundantly,

Yours sincerely,

Emmanuel
