Here we go...
"I have the exact same problems and complaints that the other negative reviewers wrote here. I installed the free version of the extension and it worked sometimes and had NO options."
Which problem is that? Unless you are uploading 25MB pics and causing your own server to choke, the plugin works flawlessly even on the crappiest servers.
"Basically this "free" extension is just an attempt by the owner, JoomlaWorks, to upsell you to buy their pro version which they advertise as being full of photo layout features. So I bought it for $20 and it doesn't work with Joomla, as noted in the other negative reviews here!!"
The Pro version is indeed more powerful. But we don't force you to buy it. People use the free version in literally hundreds of thousand of sites. They do that because it's good in providing, well, a "simple image gallery". Downloads from our site for the free version have surpassed 2m last time I checked. So I'll assume you're uploading 25MB pics on a shared host... You'd need a cluster to convert galleries of 25MB pics...
"Do NOT install this free extension nor buy their Pro extension!! Just like the other users who wasted their time wrote, the JoomlaWorks extensions do NOT work"
That is really your assumption...
"...and their support wants Super Admin Control Panel access to your Joomla site to change your core Joomla files to make their faulty extensions work!!! No way I'm giving someone I don't know over the Internet ACP access to my site so they can change core files, delete files, and screw up my whole website - just to make their defective extension work!!!! Stay away from JoomlaWorks and their extensions!!"
Your problem was clearly server related. We always ask our customers login credentials in order to provide thorough support, which, if you think about it, most of the times is not even remotely related to our extensions. Crappy hosts, bad permissions, badly written extensions causing issues and the list goes on. You may not know JoomlaWorks cause you maybe new in this community. If JoomlaWorks was "thin air", we wouldn't be around since 2006, nor distribute some of the best free extensions in the Joomla! community.
Bad developers are indeed quickly identified in open communities. But so are bad, angry users, who don't read any documentation and have no patience at all...
