Reading images

There are multiple different sources for your images. Let's look into three of the most popular methods:

• Reading images from disk
• Reading images from URL
• Reading multiple images in a folder

Start by loading the Images package and verifying your current working directory using pwd:

julia> using Images
julia> pwd()
"/Users/dc/reps/packt-julia"

If pwd does not correspond to your project folder, you have two options:

• Start Julia from a folder that does correspond
• Use the cd function to change it

The cd function accepts a single argument—the local path. An example of using the cd function would be as follows:

cd("~/repositories/julia-hands-on") # Unix-like systems
cd("C:\\repositories\\julia-hands-on") # Windows users

When you are all set, you can proceed to load your first image.
