hi, thanks for tagging me and asking for help, I have prepared a line of code to help you, I hope it will be useful for you.

you can do this using a variable and bindKey

local isImage = false

addEventHandler("onClientRender", root,
    function()
       if(isImage) then
          dxDrawImage(...) -- draw image if isImage true
       end
    end
)

bindKey("o", "down",
    function()
       if(isImage) then
          isImage = false
       else
             isImage = true
       end
    end
)

Better to remove event handler while not using. Also watch out for a pyramids if and else

local isRendering

function renderImage()
	dxDrawImage(...)
end 

function bindKey()
	isRendering = not isRendering

	if (isRendering) then 
		addEventHandler('onClientRender', root, renderImage)
		return true 
	end 

	removeEventHandler('onClientRender', root, renderImage)
end
bindKey('o', 'down', bindKey)

thanks for trying to add comments but your code is not working i think you need to improve this code or i can do it for you...

bindKey has the same name as your function

 

local isRendering

function renderImage()

end 

function bindRender() --change this
    isRendering = not isRendering
    outputDebugString(isRendering)
    if (isRendering) then 
        addEventHandler('onClientRender', root, renderImage)
        return true 
    end 
    removeEventHandler('onClientRender', root, renderImage)
end
bindKey('o', 'down', bindRender)

Oh, my bad. Didn't think about this
