	end
end

No errors but image doesn't appear.
I also want only one image to appear but I don't know how to do it.

At first - you use two functions with the same hook, what will lead to crashes/bugs if third argument isn't passed.

In second function you presented us here you will draw image only at player with ID 1.

The worst thing you did here:
images drawn every second without removing them.

The very first question I should ask is what are you trying to do?

The answer would be : this is my first time using something like "image" in lua scripting.

1. Remove this annoying meme.

2. Read it one more time http://www.cs2d.com/help.php?luacmd=image

3. You didn't explain what your script is going to do.

function array()
	local a = {}
	for i = 1, 32 do
		a[i] = 0
	end
	return a;
end

plr = {images = {weapon = {image = array(), used = array()}}}

addhook('join', 'joinHook')
addhook('select', 'selectHook')

function joinHook(id)
	if plr.images.weapon.used[id] == 1 then
		plr.images.weapon.used[id] = 0
	end
end

function selectHook(id, type)
	local a = 2
	if type == 50 or type == 53 then
		a = 1
	end
	if plr.images.weapon.used[id] == 1 then
		freeimage(plr.images.weapon.image[id])
	end
	plr.images.weapon.image[id] = image('gfx/sprites/text'..a..'.bmp', 1, 0, 200 + id)
	plr.images.weapon.used[id] = 1
end

The join hook is just to prevent some errors when people join on an already used ID. Not really needed tbh, but it works.

1. It disappeared.
2. I read it.
3. It's quite obvious when you look at hook and IF.

It's not quite what I have in my mind that I scripted but similar.
Idea :

If player has harmful weapons/equipment in inventory he gets image that says "armed"

If player doesn't have such weapons he gets image "unarmed"

This is checked every second

I hope there is a way to check if has player has items in inventory..

I am cool

" "}" expected to close "{" at line 3 near unarmed"
The error I get. Although I can see there is "}" in next line ...

arm.images = {

     unarmed = 'gfx/sprites/text2.bmp'
}

Is the correct version. You need commas in table constructors.

arm.img.unarmed = arm.initArray(nil)

That is a waste of code! If a table field is set to nil, the field is empty, that is it doesn't exist! You don't need this, it will work if you just replace it with:

1
2

arm.img.armed = {}
arm.img.unarmed = {}

Unless I missed something you also lack a declaration for arm.img. So you'll need to place this after arm = {} :

arm.img = {}

I did everything that EngiN33R said.
2 hooks are added but it doesn't work.
When I appear I get the "text2" image. That's fine since I own knife but when I take weapon like m4a1 it still says I'm unarmed even though I have lot's of things that are weapons and harmful..

I found bug in lua about playerweapons(id)

It's not a bug, just normal. Spawn hook is called when player is being spawned what mean, in that moment player doesn't have any weapons. After some microseconds yes, that's the reason player can't always get items with parsing equip command, but by returning string with items to equip.

You didn't listen what Engin33r had said.

arm.img.armed = arm.initArray(nil)

Lua is dynamically typed language what means that all variables can be declared in every part of script. Setting nil as value is stupid, becouse all undeclared variables have "nil" as value by default.
