If I remember right you have altered your importer to work with different images and even a different albinator type.
When we import the photos we write a query to the photos row. I would suggest you redownload the normal importer and work forward. Obviously there is an edit you have done to not allow the query to work. I show the query to be sound and there should be an error on screen if you have an issue. Next the imagesizes are UPDATED in the photos table when we import the file. This importer works fine with the normal coding on albinator basic. Albinator has not been sold for years and all I own is basic. I have tested an import and all works okay so look to the coding changes you made to grab different files.
