I'm trying to follow this example on how to draw a background grid so I can easily connect arrows, but it draws the (non-transparent) picture on top of the grid making it hard to use. I want to draw the grid in the foreground, how can I do that?

Using the markings
library you can instruct tikz to draw the arrows on a top layer. This requires changing the edge
notation to to
(as edge
doesn't seem to add to the path so that the marking can be applied).
\documentclass{standalone}
\usepackage{tikz}
\pgfplotsset{compat = newest}
\usetikzlibrary{arrows.meta, decorations.markings}
\pgfdeclarelayer{arrowlayer}
\pgfsetlayers{main,arrowlayer}
\tikzset{%
state/.style = {%
draw, circle, minimum size = 4, inner sep = 0, fill = black
}%
}%
\tikzset{%
dashedarrow/.style = {%
draw, densely dashed, > = {Latex[width = 1.7mm, length = 2.2mm, open, fill = white]},
decoration={markings, mark=at position 1 with {\begin{pgfonlayer}{arrowlayer}\arrow{>}\end{pgfonlayer}}},
postaction={decorate}
}%
}%
\begin{document}%
\begin{tikzpicture}%
\node[state] (0) at (0,0) {};
\node[state] (1) at (1,0) {};
\node[state] (2) at (0,1) {};
\path[dashedarrow] (1) to[bend left = 20] (2);
\path[dashedarrow] (2) to[bend left = 20] (0);
\end{tikzpicture}%
\end{document}%
This is discussed at length in section 4.27 of the pgfplots manual. All I did is to define a new layer set based on axis on top
in which I flip the order of axis grid
and main
.
\documentclass{article}
\usepackage{pgfplots}
\usetikzlibrary{shapes.geometric,arrows,arrows.meta}
\pgfplotsset{
/pgfplots/layers/Bowpark/.define layer set={
axis background,axis grid,main,axis ticks,axis lines,axis tick labels,
axis descriptions,axis foreground
}{/pgfplots/layers/standard},
}
\begin{document}
\begin{tikzpicture}
\begin{axis}[width=\textwidth,
xmin=-0.5, xmax=6,
ymin=-0.5, ymax=4,
axis line style = thin,
axis lines=middle,
axis line style={-{Stealth[length=2.5mm]}},
thick,
grid=major, grid style={dashed,gray!30},
set layers=Bowpark]
\addplot[blue, samples = 100] {x^2};
\end{axis}
\end{tikzpicture}
\end{document}
EDIT: Fixed bug, I was too sloppy, sorry!

You can temporarily use
opacity=.5
for the node where you insert the picture:When you are done, simply make
opacity = 1
or delete it.Full code:
Or using a
scope
to draw them after including image.PS: I have used
example-image
frommwe
package. Change it with your picture.
