[TriLUG] Odd website behaviour

[William Sutton]

1. Did you check the full img URL path, as generated by your application, 
from your web server?  Did it work?  (probably not)
2. Is the URL path correct based on the web root + relative image path?
3. are the permissions on the various directories, from the web root down 
to the images themselves, correct?
