In /etc/allmon3/web.ini there is a setting for CONFIG_HEADER_LOGO and it takes the filename as input and prepends the [A,a]llmon3/img/ path:
; CONFIG_LOGO_IMG appears aligned right in the top-right corner
; of the page. The max height of this image should be 50px. If
; you do not want a logo to appear, leave this entry as an
; empty string "" and the ASL logo will be display. Image
; file is relative to the img/ subdirectory of Allmon3
CONFIG_HEADER_LOGO = ""
Adhering to the maximum image height, specifying the “filename.ext”, storing it in /etc/allmon3/img/filename.ext, and making it world readable results in a 404 error for the image. Restarting of the host and refreshing the browser cache does not rectify the error. Also, storing the image in /var/www/html/allmon3/img/filename.ext doesn’t resolve the error.
Any ideas? Thanks in advance!
