[opencms-dev] Opencms 10 - Opening any image gallery folder -> no image is shown !? :(

[always.work.in.progress always.work.in.progress]

hi all,
i am experiencing the following problem:

problem description:
Inside Workplace Explorer:
Opening any Image Gallery folder (type "image gallery") through context
menù related command "Open gallery" ->pops out normal workplace window
but *none
of images present in the gallery are shown *!? :(
(neither through manually filtering through "galleries" and picking any of
them are shown)

note:
no output errors are shown in browser neither in opencms.log file
normal .jpg images are present inside image gallery folder type (and
clicking onto them, i can open them inside the browser)
nothing changes if i publish or not the image gallery folder
problem is presenting with all browser (Firefox, Chrome, IE)
i have checked "/system/workplace/commons/open_ade_gallery.jsp" file, that
i know is called from "Open gallery" menu command,
and it is present.

Environment:
Linux Centos/tomcat/java - Opencms 10.0.0 - multisite configuration with
apache + mod proxy as stated in
http://documentation.opencms.org/opencms-documentation/server-installation/apache-webserver-configuration/

Are there any Opencms configurations/settings/files i should check in order
to solve the problem ?

thanks in advance,
A.
