Hi,  
I think the behaviour of show() has changed recently. Calling:

```julia-auto
using Plots
p = plot(rand(10));
png(p, tempname())

```

always shows the plot.

Same for:

```julia-auto
using Plots
p = plot(rand(10));
io = PipeBuffer()
png(p, io);
# or
show(io, MIME("image/png"), p)

```

Is there any way to suppress it or is it a bug?

One way to disable showing the plot is:

```julia-auto
using Plots
p = plot(rand(10));
withenv("GKSwstype" => "100") do
    png(p, io)
end

```
