Images set "restful_urls=On" by default.

[marcbria]

When you visit your site, you are redirected to "/index/install" (without index.php).

It happens because default images are setting "restful_url=On" when by default OJS sets this to "Off".

This is an unexpected behaivour not documented and difficult to track (once could think is related with virtualhost, htaccess, etc).
The project's philosophy is to keep images as tight as possible to PKP's original code (that is what users will expect), so it need to be changed. If we like to change this it could be a env-variable or setting config.inc.php as a file-volume or using ojs-variables helper script, etc.

Once we revert this change, this will need to be properly explained.

Labeled to fix in next release.
