Hi and welcome.  
This appears to be using a very old version of ImageMagick.jl, since the error ultimately comes down to using `BinaryProvider`, an older component which was [removed in 2019](https://github.com/JuliaIO/ImageMagick.jl/pull/168).  
Have you updated to the latest version (currently 1.2.2 at time of writing)?

Thank you @jd-foster. Just a bit of details.

I used following command to install latest package:

```julia
Pkg.add("Images", version="0.25.2")

```

This errored out saying I had older `Luxor` package, which was restricted to that because of `ThinkJulia` package. I removed the later and reran the above command to successfully install `Images`.

Also, I am now noticing the `Info` post installation. `Julia` identifies packages with latest version available but cannot upgraded due to combability restrains. I will keep an eye on that.

Thank you again!!
