Hi. I am working on localhost, so in my case no admin nor ftp send option.
I installed de quickstart that comes with the Entrepreneur template and the module was fully functional.
As soon as I deleted the images in order to put mine, the module cannot load images AT ALL it says just ''error'' (Not much of help that If I may say).
I uninstalled the module, installed it again with the one that comes with the extensions folder and no luck. The module you provide there is version 3.1
Since there are more than two people asking assistance with this module in my opinion is only logical to post solutions to all of us, in order to solve this that at this point is a problem with the module, not necessarily the host.
I looked over the permissions in folders and they seem ok.
