Thumbnails are question marks in CKFinder window

config.thumbnails = structNew();
config.thumbnails.url = 'http://www.alterheros.com/thumbnails/';
config.thumbnails.baseDir = 'c:/websites/134459jt7/thumbnails/';
config.thumbnails.enabled = true;
config.thumbnails.maxWidth = 100;
config.thumbnails.maxHeight = 100;
config.thumbnails.quality = 80;

Hi,

I am experiencing the same problem as Marc-O (mercure) with the Coldfusion version, but I am running the demo version (no license purchased yet).
We're running Coldfusion 8 and I haven't changed the config.thumbnails settings.
Wiktor - I have removed the cfcatch statements in the two files as you've suggested. When I reload the URL, I get the following response in IE7:

<Connector>
<Error number="104"/>
</Connector>

Hope this helps.
Thanks for your help.

Glenn.

Sorry for taking so long to reply. This is something I can't reproduce.
It looks to me that CKFinder is unable to create the thumbnails directory. To be sure that this is the problem, in core\connector\cfm\CommandHandler\Thumbnail.cfc paste the following:

<cfif not fileSystem.createDirectoryRecursively(thumbPath, 0755, true)>
   <cfdump var="Path: #thumbPath#">
   <cfabort>
   <cfthrow errorcode="#REQUEST.constants.CKFINDER_CONNECTOR_ERROR_ACCESS_DENIED#" type="ckfinder">
</cfif>

instead of:

      
<cfif not fileSystem.createDirectoryRecursively(thumbPath, 0755, true)>
      <cfthrow errorcode="#REQUEST.constants.CKFINDER_CONNECTOR_ERROR_ACCESS_DENIED#" type="ckfinder">
</cfif>

and open the url with the Thumbnail command once again. If the path is displayed, instead of previous XML message, it means that web server can't create the directory for thumbnails.

Hello, I have followed all the instructions for the issue and i am definately getting a file permission issue however, I dont' understand as to why.

We are on cf8 using sandboxing. I have given permission to the directories properly in the sandbox and I don't have trouble uploading or deleting files from the images directory it just doens't create the thumbnails. Also I have noticed that when an image is uploaded it keeps it in the temp directory on the server rather than moving it out after it has been uploaded.

C:\JRun4\servers\cfusion\SERVER-INF\temp\cfusion.war-tmp\
is keeping a copy of the file after uploading this should actually be removed after placing it in the site folder.

Any solutions for veiwing the images would be greatly appreciated if I can actually get this to work on one site then will be getting a Corporate Web Sites license but really need the ability to do view the thumbnails.

thanks.

Tigerlady: did you follow my suggestion postend on: Tue Feb 26, 2008 6:54 pm?
Is the fileSystem.createDirectoryRecursively function responsible for not returning thumbnails?

If you add this code, is the thumbPath displayed in the response message?

<cfif not fileSystem.createDirectoryRecursively(thumbPath, 0755, true)>
   <cfdump var="Path: #thumbPath#">
   <cfabort>
   <cfthrow errorcode="#REQUEST.constants.CKFINDER_CONNECTOR_ERROR_ACCESS_DENIED#" type="ckfinder">
</cfif>

ok I just downloaded and installed fiddler and here is what I am getting.
<?xml version="1.0" encoding="UTF-8"?>

<?xml version="1.0" encoding="UTF-8"?>
<Connector resourceType="Images"><Error number="103"/><CurrentFolder acl="224" path="/" url="/media/images/"/></Connector>

Edited 4:01 pm:

Ok i did some more digging and realized that some of my code was missing to even view the thumbnails.

config.baseUrl = "/media/";

config.baseDir = APPLICATION.CreateCFC("Utils.FileSystem").resolveUrl(config.baseUrl);

config.thumbnails = structNew();
config.thumbnails.url = config.baseUrl & 'thumbs';
config.thumbnails.baseDir = "/images/";
config.thumbnails.enabled = true;
config.thumbnails.maxWidth = 100;
config.thumbnails.maxHeight = 100;
config.thumbnails.quality = 80;

config.accessControl[3] = structNew();
config.accessControl[3].role = '*';
config.accessControl[3].resourceType = 'Images';
config.accessControl[3].folder = '/';
config.accessControl[3].folderView = true;
config.accessControl[3].folderCreate = true;
config.accessControl[3].folderRename = true;
config.accessControl[3].folderDelete = true;
config.accessControl[3].fileView = true;
config.accessControl[3].fileUpload = true;
config.accessControl[3].fileRename = true;
config.accessControl[3].fileDelete = true;

Then these are the responses I get back.

<?xml version="1.0" encoding="UTF-8"?>

Once again let me stress that I have turned on Sandboxing. I have tried everything from root right down to the directory to allow read write capabilities for this site. Still nothing seems to work properly.

It looks to me that you have accidentally set incorrect permissions.
ACL 224 means: File delete + File rename + File upload.
To be able to browse files you need also: folderView and fileView. fileView permission is also required to create thumbnails.

So first thing we need to de before debugging this thumbnail issue, is to grant all permissions to your test user to be sure that we have appropriate ACL settings.

our postings must have crossed as you can see i did go and add those and now i am getting a java file permission issue.

Ok, so we have found the error: "access denied (java.io.FilePermission \images\Images read)".
I'll try to reproduce it tomorrow and we should have it fixed soon, thanks!

There is one more thing that you could try:
Copy the url of the command that sent this error and open it in your browser.
java.io.FilePermission is not as helpful as detailed exception iformation, so let's change the code a bit to get the whole exception:
Comment out the catch "any" statements:

<cfcatch type="any">
...
</cfcatch>

in connector.cfm, Connector.cfc, CommandHandler/XmlCommandHandlerBase.cfc.
You should be able to see the detailed exception information (assuming that "Enable Robust Exception Information" is checked).

Ok I tried it and it still isnt' working.

I sent you a private message.

I even renit the application.

Is there soemthing else I should try?

did you want me to uncomment the error code from the previous post?

still get this in the error email

I replied to your private message but it still says sitting in my outbox. can you confirm if you got the pm? thanks.

config.thumbnails = structNew();
config.thumbnails.url = config.baseUrl & '_thumbs';
config.thumbnails.baseDir = config.baseDir & '_thumbs';

config.thumbnails = structNew();
config.thumbnails.url = "http://example.com/ckfinder/userfiles/_thumbs";
config.thumbnails.baseDir = "/absolute/path/to/www/example.com/ckfinder/userfiles/_thumbs";

Is it possible that safe_mode is enabled on your server?
Open _thumbs folder, CKFinder created there another subfolders, one per resource type. Check permission and owner/group of those subfolders. It may be that CKFinder is unable to write to _thumbs/Images to save there thumbnail of myfile.jpg.

Permissions of subfolders of _thumbs folder are set to "777".
Safe_mode of php is set to "ON"

You might need to disable safe_mode. It doesn't improve your webserver security and another drawback is that it is impossible for a PHP script to operate on folders created by the same script.
CKFinder created automatically subfolders inside of _thumbs directory and because safe_mode is on, it is unable to save thumbnails inside of those directories (even 777 doesn't help, because probably the owner/group of a subfolder is invalid).

My hosting provider is refusing to disable safe_mode. Is there other solutions?

I'm affraid not at this moment. The only solution for a server with a safe_mode enabled is to use ftp_* commands to create folders which means that you would have to change the CKFinder core to achieve this functionality.

try resetting the permissions for the _thumbs directory. I recently found that although I had set the permissions correctly prior to actually using the editor for some reason the 777 setting did not stick and I was getting the the ? for thumbnails as well. Once I set the permission again for the _thumbs directory to 777 the Thumbnails started working.
