broken demo: "Cropping, Resizing and Rescaling"

[johnnychen94]

I don't see any code results and a cover is missing for demo: Cropping, Resizing and Rescaling, @ashwani-rathee could you please help fix this?

@johnnychen94 Sure,though I did test it before pushing it online...can you tell what could be the issue?

According to the CI log(e.g., https://github.com/JuliaImages/juliaimages.github.io/runs/2118016729), it seems that we need to add ImageTransformations to Project.toml.

This happens when you have ImageTransformations installed in your root project. When a package is not specified in Project.toml (or more correctly, in Manifest.toml) of the project folder, julia will try to find and load it in DEPOT_PATH order:

julia> DEPOT_PATH
3-element Vector{String}:
 "/Users/jc/.julia"
 "/Applications/Julia-1.6.app/Contents/Resources/julia/local/share/julia"
 "/Applications/Julia-1.6.app/Contents/Resources/julia/share/julia"

In my case, Julia will finds this package in /Users/jc/.julia/environments/v1.6/Manifest.toml. However, every build in CI is a clean setup, so Julia complains about it.

@johnnychen94 Okay,I'll just update it with ImageTransformations addititon,Should I create another PR for that or can the merged PR can be reverted and opened again?

[johnnychen94]

When a PR is merged, it can only be reverted. So yeah please create a new PR.
