GSgallery (Simple Image Gallery) - Images Don't Appear

[angiebell13]

I have GetSimple version 3.1.2. that I'm making a small website with for school and I'm trying to use "GSgallery (Simple Image Gallery)" by Square It Solutions to display a gallery of images. I'd like my gallery to have captions and descriptions. I haven't figured out if there's a way to have descriptions. I've read a bit in the forum where people have had trouble with this Plug-In and it seemed like permissions and the version of PHP that is running were two issues that people asked about. I'm using FatCow as my web host and I have PHP version 5.3.13. So my website isn't locally run, but it's on a server. The folder the images are in is 774 I believe. I'll clarify that in further detail. My images only display when I'm logged in. Any ideas as to why that is the case?
