friends
i have posterbox and i want to put text in this box.
Please see image

Minimal working example:

documentclass{article}



usepackage{tcolorbox}

tcbuselibrary{poster}

usepackage{tikz}



usepackage{lipsum}



begin{document}



begin{tcbposter}[

  poster = {

    columns=1,

    rows=2,

    spacing=3mm,

    height=14cm,

    width=12cm,

  },

  ]

  posterbox[

  colframe = red,

  width=13cm, height= 10cm

  ]{ }{includegraphics[height=4cm]{example-image-b}}



end{tcbposter}



end{document}

Add "ABC" and "XYZ" like attached image
Thanks

With skin library you can draw whatever you want on a tcolorbox, with exact coordinates.

documentclass{article}

usepackage{geometry}

usepackage{tcolorbox}

tcbuselibrary{skins}

pgfsetlayers{main}

begin{document}

begin{tcolorbox}[

  width=13cm,height= 10cm,

  skin=freelance,

  interior code={%

    path (frame.south west) -- (frame.south east) node[midway,above=1ex,font=Largesffamily] {ABC};

    path (frame.south east) -- (frame.north east) node[midway,rotate=90,above=1ex,fill=yellow,font=Largesffamily,inner sep=8pt] {XYZ};

  },

  frame code={%

    begin{pgfonlayer}{main}

      path[draw=red,fill=gray!20,ultra thick,rounded corners] (frame.south west) rectangle (frame.north east);

    end{pgfonlayer}

  },

]

includegraphics[height=4cm]{example-image-b}

end{tcolorbox}

end{document}

You can use ordinary TikZ commands in a tcbposter environment.

documentclass{article}



usepackage{tcolorbox}

tcbuselibrary{poster}



usepackage{lipsum}



begin{document}



begin{tcbposter}[

  poster = {

    columns=1,

    rows=2,

    spacing=3mm,

    height=14cm,

    width=12cm,

  },

  ]

  posterbox[

  colframe = red,

  width=13cm, height= 10cm

  ]{name=A,column=1}{includegraphics[height=8cm]{example-image-b}}

  node[font=sffamilyLarge,rotate=90] at (12,9.6) {XYZ};

  node[font=sffamilyLarge] at (6,5) {XYZ};

end{tcbposter}

end{document}

Or you can position these nodes relative to the picture.

documentclass{article}



usepackage{tcolorbox}

tcbuselibrary{poster}

usetikzlibrary{positioning}

usepackage{lipsum}



begin{document}

begin{tcbposter}[

  poster = {

    columns=1,

    rows=2,

    spacing=3mm,

    height=14cm,

    width=12cm,

  },

  ]

  posterbox[

  colframe = red,

  width=13cm, height= 10cm

  ]{name=A,column=1}{includegraphics[height=8cm]{example-image-b}}

  node[font=sffamilyLarge,rotate=90,right=-5mm of TCBPOSTER@A]  {XYZ};

  node[font=sffamilyLarge,below=-10mm of TCBPOSTER@A] {XYZ};

end{tcbposter}

end{document}

Or you can just use a table and rotatebox.

documentclass{article}



usepackage{tcolorbox}

tcbuselibrary{poster}



begin{document}



begin{tcbposter}[

  poster = {

    columns=1,

    rows=2,

    spacing=3mm,

    height=14cm,

    width=12cm,

  },

  ]

  posterbox[

  colframe = red,

  width=13cm, height= 10cm

  ]{ }{begin{tabular}{cl}

includegraphics[height=4cm]{example-image-b} &rotatebox{90}{XYZ} \

XYZ & 

end{tabular}}



end{tcbposter}



end{document}
