Installed Zoneminder 1.24.2 on centos 5. I can add cameras and see the video and the events trigger fine. When I click on the event I don't get the picture. Only an empty box where the picture should be. When I go to edit the zones, the same thing happens, no images. I initially installed 1.23.x and had the same issues and went to 1.24 after some digging to see if that would fix the issue. If I go into the directory where the images are stored using smb, the images good and contain the analyzed phots and everything.

I have tried searching various terms with zones and blank pictures and just come up empty handed. I have tried the FAQ with no results. Maybe I missed something but I followed an install tutorial to get it installed.

What am I missing?

Thanks,

open up and take a look at the zm logs

check the image directory to see if it is really soring events

After finding the logs in /var/log/messages instead of /tmp (DOH!) I figured out what was going on. I have an mounted directory for the events and I was using absolute paths in the config. According to the logs it was trying to get the images from the zm web folder/mnt/zone. So I mounted the fs to a folder in zm and changed the config. This allowed the events to be replayed.

I still don't have images for zones though. When I go into a zone I see the following error message in the log:
Jul 19 18:09:34 centos zmu[4253]: ERR [Can't open Zones4.jpg: Permission denied]

There are no ZonesX.jpg images on the filesystem. What would the path to this file be?

did you make sure that apache user has full access to the directory/filesystem chown and chmod

Posted: **Thu Jul 30, 2009 2:20 am**

drwxrwxrwx 5 apache apache 4096 Jul 29 19:13 zone

Cant get much more open than that. Is there a way to get it to tell me the path which Zones9.jpg is supposed to be at?

The shows:

When I try to access the zones.

zone images should be located at:
{web_directroy}/images

I am having a similar problem. I just installed a machine with 1.24.2 on Ubuntu. I get alarms and can generate Video's and see still images but can not see live windows, Zone setup images, etc.

Previous on another machine I had 1.24.1 installed and didn't have this problem.

I have no errors in the message log. Any suggestions?

Thanks

nstalled Zoneminder 1.24.2 on Fedora 10 x86_64. I can also add cameras and see the video and the events trigger fine. When I click on the event I don't get even the blank picture window. Camera is set to Mocord. When I select the events associated with the camera and "Events windows" opens and I select "Show Timeline" everything appears as expected. Still unable to play back any events.

I have tried searching various terms with zones and blank pictures and just come up empty handed. I have tried the FAQ with no results. Maybe I missed something but I followed an install tutorial to get it installed.

I was having a similar problem where zone images were blank.

When I looked in {web_directory}/images I found images like Zones1.jpg, however the Apache log indicated it was looking for files named like <monitor_name>-Zones.jpg.

I tracked the problem down to zm_monitor.cpp where it was naming the image files differently than what zm_html_view_zones.php was expecting.

So I changed zm_monitor.cpp as follows and zone images are working for me again.

I haven't been keeping up with ZM for a while. Is there a way I can submit this so it gets rolled into trunk? (Assuming my analysis was correct of course)

You can disregard my previous post. The problem I had was that when I upgraded from 1.23.3 to 1.24.2 all the original web interface files from 1.23.3 remained in the web directory. I renamed the existing web directory then did a make install to copy the 1.24.2 files over again. This cured the majority of problems I was having.

I had the issue where the zoneeditor was not displaying the image and going to http://127.0.0.1/zm/images showed an empty directory.

This forum article helped (thanks kingofkya). I found that the images folder ownership was 'root' rather than 'www-data' (I'm running the debian package on ubuntu as it's more up-to-date): -

I altered the ownership thusly and now see zoneimages as expected/desired: -

Thanks, i had the same issues with no zones and no events. Thought i would have to re-install zoneminder.

Changed the owner to www-data and it solved the issues. Great
