Squid Custom error page (Where to put picture files?)

[DaBeach]

I am attempting to modify the error page "ERR_ACCESS_DENIED" and add a picture by adding the HTML "" however, I can't seem to get it to pull the file even if it is in the /usr/local/etc/squid/errors/English directory.

If using the HTML code above would it not pull the image file from the same directory?
