1) The errors about "galleryXX.jpg.htm" is actually a problem with the Minis Gallery page. The links are incorrect on the page. But I posted a new version that replaces the incorrect urls with the correct ones.
2) The errors about write during creation is a separate issue. My best guess is that the utility does not have write access to folder it is in. The application must be able to create files and folders in the folder in which you are running the utility. It creates the module in its own folder and when complete moves it to the FG folder.
