| One line summary
|| The collection contains a mix of uncompressed and compressed TIFF files. The compressed TIFFs are not read correctly when derivatives are programmatically created.
| Detailed description
- Compressed and uncompressed TIFF images (possibly other formats) mixed in together, causing problems for building derivatives with PIL (Python Imaging Library). The PIL is not able to read Group 4 compressed TIFFs and so cannot create JPEG derivatives.

| Possible approaches
- Use a tool such as FITS (File Information Tool Set) to identify the file type and rate of compression of each file in the collection
- Script an open source imaging application such as Imagemagick or GIMP to convert compressed TIFFs to uncompressed TIFFs
