julia> using FileIO

julia> load("img.tiff");

Errors encountered while load File{DataFormat{:TIFF}, String}("img.tiff").
All errors:
===========================================
ImageIO load error: neither load nor fileio_load is defined
  due to MethodError(size, (ERROR: MethodError: no method matching size(::TiffImages.DenseTaggedImage{ColorTypes.RGB{FixedPointNumbers.N0f8}, 2, UInt32, Matrix{ColorTypes.RGB{FixedPointNumbers.N0f8}}})
The applicable method may be too new: running in world age 29613, while current world is 29623.
Closest candidates are:
  size(::TiffImages.DenseTaggedImage) at /Users/ian/.julia/packages/TiffImages/ZnhmN/src/types/dense.jl:24 (method too new to be called from this world context.)
