[Plugin: Image Store] Various

I have various problems:

1 – The gallery names in not displayed below them, instead the featured image’s name is.
2 – How doe albums work? I have tried to set up albums, and have managed to, but how does this feature actually used?
3 – When customers want to view a bigger image of the one they want to buy, the image size when you click on the thumbnail is too small. How do I make sure they are large enough to view properly?
4 – The image store support forum on X-park media doesn’t work.
5 – I need a user manual to show me how to operate this plugin.
