Thumbnail appears broken for any image upload in G2

I recently decided to setup and play around with G2 before migrating my
existing G1. I have successfully setup G2 (all steps). Then I have this
weird problem with the thumbnails.
Basically, I added sample images. They were added fine except that
thumbnails show up as broken. javascript:emoticon(':cry:')
javascript:emoticon(':cry:') Clicking on the broken thumbnail does load
the actual full image as you can see. I have ImageMagik and NetPBM both
graphics toolkits installed and setup the preference to use ImageMagick first. In siteadmin under ImageMagick and NetPBM both pass all the
tests successfully.
Best way to understand this is simply look at my sample site listed
in below url. Any help will be much appreciated. I have supplied all info below for faster troubleshooting. Thanks.

I did not just activate modules. I have both IM and NetPBM binaries installed in
/usr/bin and path has been specified properly. All tests pass successfully. See below
output. It is worth noting here that the same server also hosts my production G1
which uses same version of IM and NetPBM just fine.

Anyway, following is the output that "Test Settings" button reveals:

ImageMagick binary test results

Version
ImageMagick 6.0.7

Supported MIME Types
The ImageMagick module can support files with the following MIME types:

image/gif
image/jpeg
image/pjpeg
image/png
image/tiff
image/svg+xml
image/bmp
application/photoshop

Help! Anybody, please. Thanks!!

Valiant,
I have indeed activated modules after installing. I also tried deactving others and
leaving only ImageMagick as per your suggestion, still no luck. I did upload file
again after doing to see if new file's thumbnail is created properly or not.

Finally, I also activated immediate debug and got something worth paying
attention. I was trying to upload a image file named "school_of_rock.jpg".
Now see the debug log below:

As you can see above that ImageMagick was not able to read the file "school_of_rock.jpg" due to permission denied. So, next I checked the permissions
in /var/www/g2data/albums directory and file was listed with 600 permission
although I have setup in General section of SiteAdmin to use 644 as file and 755
for directory permissions and my g2data directory has 777 permissions.

See below all the permissions setup on g2data directory/subdirectories.

[root@parikh www]# ls -ld g2data/

-rw------- 1 apache apache 124193 Mar 21 12:23 School_of_Rock.jpg

Funny thing is that its just the thumbnail that shows up broken, clicking on it does
load the actual image, so apparently apache can read it as you can see from
above permissions that apache has permission to read it. I don't know why its
being set to 600 although I have set it to use 644 in General/SiteAdmin section.

So question is that is ImageMagick being run ander apache user in G2? If so, then
it should be able to read the permissions and file as apache is able to. And if not,
then why G2 sets the permission of 600 after file upload eventhough I select it
to be 666 in General/SiteAdmin section? I don't know if anybody else is having
these issues. Any help would be much appreciated. Thanks.

Something is going wrong when we try to create the thumbnails. Here're the steps to debug it. As a side note, we don't put thumbnails into the g2data/thumbnail directory (that's for the thumbnail module; which is a little different).

1. Right click a thumbnail, get the url and open it in a new browser window so that all you can see is the broken thumbnail image.
2. Edit your config.php and set G2 into "logged" debug mode. Provide it with a path to a log file. Make sure that this works (reload G2, then check the file to make sure it has data in it). When you're done testing to make sure it works, clean out the file so that it's ready for our test.
3. Delete g2data/cache/derivative/*
4. Reload the thumbnail in your browser. Remember you want to load only the thumbnail
5. Turn off debug mode (or else that file will get huge!)

Now you should have a logfile containing all the debug output from building the image. In that logfile should be the commands we executed to try to generate the thumbnail, as well as the errors that it encountered. Post a link to that log here and we'll check it out.[/]

Hmm. Here's why it failed:

2005-03-22 10:29:47 [3e9d1b2973054212593673fb730b387d] Error Output:
2005-03-22 10:29:47 [3e9d1b2973054212593673fb730b387d] convert: unable to open image `/var/www/g2data/albums/DSC00912.jpg': Permission denied.

Looks like more of your permission issues. I'm not sure what's going on here, but it's pretty clear that it's a permissions issue. As a test, how about you do a "chmod -R 777 g2data" so that the permissions issue goes away? If that fixes it, then you'll need to talk to your system administrator to figure out what the permissions and ownership should be. It's odd that Apache will let you create files that it can't read so something deeper is going on here...

could you please post:

and please check tell us what filesystem permissions the file in g2data/albums/ has that you just added via add items -> from web page.
