Unable to batch upload images

I am not able to upload images via csv import or batch update on back-end Manage Property screen. In both cases the image folders are showing up under images/osproperty/properties with no images.

I have tried to batch upload as few as 10 images at about 50kb each, so it's not a size issue. Also, uploading individual images works just fine.

I am running Version 2.4 on Joomla 3.2 on a LAMP server.

Any thoughts?

Hi Tom,
Are you working on localhost? Can you please upload your site into demo server so both you and me can check the issue
Thanks

The site is up on affourhl.info

It's very much unfinished so the navigation is a little weird - click on "Rentals" on the splash screen and you can see the listing. Let me know what else you need.

Thanks!
