after remove all report files, re-generate report the logo breaks, images&css stylesheet files were gone and will never be created

[jm0477]

output folder:
/var/www/squidanalyzer

configure file:
/etc/squidanalyzer/squidanalyzer.conf
Output /var/www/squidanalyzer
WebUrl /squidreport

after run squid-analyzer, the /var/www/squidanalyzer/images and css folder were not created automatically. the staticstics were generated correctly, but style lost and logo is missing.
How to resolve this issue? it is by design or any parameter can resolve it?

I found the solution.
I need to make && make install to get the iamges/css back.
