No support, minimal docs

I’ve installed and tried to use Gmedia on a prototype personal photography site. I’m an experienced (20 years) webdev and photographer (a lifetime!). Gmedia looked to be a good plugin with lots of capabilities, not least metadata support. However, there’s minimal documentation, just a few ‘use cases’, and support is non-existent. Zilch. Nada. Bubkes. The interface is less than intuitive, and uploading of photos often generates a “File is not an image” error when I know full sodding well that it is, having taken the photo myself and uploaded elsewhere. I’m giving up on Gmedia, sadly as I’ve uploaded a lot of photos to it and I’ll have to redo this, because it’s unsustainable and unreliable.
