[chowalit.lab Chowalit Lab Linux]

Dear all,
      I have my own ERR_ACCESS_DENIED. I try to insert my logo into
error page with this code

<td background=<IMG SRC="logoproxybg.png" WIDTH="5" HEIGHT="72"
BORDER="0" ALT=""><center><img src="logoproxy.png" width="720"
height="72" border="0" alt=""></center></td>

    It wasn't display my image (i.e. logproxybg.png, logoproxy.png).
I put these images into /etc/squid/errors.  How to show this image?

Thanks
