FlexSlider_Fields don't load images with IMCE module if they are within subdirectories

Thanks for the module, it's amazing, but I find a problem: FlexSlider Fields don't load images with IMCE module if they are within subdirectories.

When I use the IMCE module to load the images from the server, only load the images if they are in a root folder. If the images are sorted into subdirectories, Flexslider not load.

IMCE module seems to load the images as .tmp but then renames the original extension (.jpg in this case) but Flexslider Field reads like .tmp and no load. Launching the following error:

The selected file p19gid8db87epcgg1qol59p1t9a5.tmp Could not be referenced. Only allow files with the following extensions: png gif jpg jpeg.

and if the pictures folder has been uploaded by ftp, direct does not show the images. IMCE Wysiwyg API with bridge load the images perfectly. Both via ftp as plupload.

I believe that maintaining an order of the images in our server is essential. Don't believe?

Any suggestions?
