When i try to upload images via elfinder through drag and drop i have no problem they are uploaded, when i try the same for a folder that has images i get the following error.

"Unable to connect to backend.
Connection aborted."

I have folder that have a number of folders with images. Uploading them one by one takes a lot of time does anyone know how i can bypass it.

I had though of uploading a zipped file and then extracting but elfinder doesn't have that provision for extracting.

Anyone out there kindly help.
Muchas gracias

elFinder is meant for files that are not gallery files. I have no idea if it is meanto upload folders as it is a 3rd party tool we just included. My colleague might know more.

If you wish to upload to your albums you should use the separate album upload.

The error is from the elFinder software itself. It means that the connection from the browser JavaScript code did not get a response back from the server side code. More than that I do not know.

When you do the drag, does you filemanager indicate that it is doing a "move" or "copy"? When I try this Windows decides that it is doing a "move". elFinder does get the "folder", but it still refers back to the desktop filesystem, so is useless.

You should try a different browser to be sure it is not a browser issue. Can you upload files?

Other than that visit the elFinder forums and see what you can learn there.
