8431	CKFinder thumbnail creation in sub-folders of a 2nd-level folder not working	Jonny N		"If CKFinder is being used to browse an *existing* folder structure of images for the first time, and is therefore creating thumbnails on-the-fly whilst exploring the folders therein, it *won't* create thumbnails for images in sub-folders of a folder that contains no images (only sub-folders) itself. For example:

Images/folderX[[BR]]
+ folderA[[BR]]
(  imageA.gif)[[BR]]
+ folderB[[BR]]
(  imageB.gif)[[BR]]

..when you navigate into 'folderA' or 'folderB', thumbnails for 'imageA.gif' and/or 'imageB.gif' don't get created, seemingly because 'folderX' itself doesn't contain any images, only the sub-folders 'folderA' and 'folderB'.

The same behaviour exhibits for further levels of folder nesting (e.g. in 'folderA' or 'folderB' had further sub-folders within them).

As I mentioned already, this behaviour *only* occurs when exploring an existing nested folder structure of images and sub-folders for the first time with CKFinder. When folders are created or images uploaded by CKFinder itself, thumbnails are created as expected.

Bug exhibits regardless of which browser is being used, tested on many! I'm using the PHP connector.

When such a sub-folder is navigated to, the file browser sends a request to the connector for the thumbnail, but the response is always empty. This appears to be because the parent sub-folder doesn't exist within the thumbnails directory (as it hasn't been created, as 'folderX' has no images in). The connector back-end should cope with this scenario and recursively create the required sub-folders in the thumbnails directory if they don't exist."	Bug	closed	Normal		File Browser		invalid
