Image import is not working in WordPress
I'm using WooCommerce Amazon Affiliates plugin (codecanyon) for wordpress, which import products from Amazon including images, reviews etc. Everything seems to be working fine and even it's shows message that images are downloaded from Amazon but they're missing. It's not importing images in wordpress uploads folder. Folder permissions are also fine. I checked plugin on my pc localhost (UwAmp) and another hosting and images are working fine there. I'm running Ubuntu 12.04.3 x32. Any help would be really appreciated.
