You don't have a contiguous list, for example, if ct_gfx is called in the following order:

1, 2, 32, 5

and then free_all is called, then only player 1 and player 2's images will be freed because ipairs is an incremental iterator.

You can try to use a variable for loop

1
for id=1,32 do freeimage(ct_img[id]) end

However, this will return errors if ct_img[id] doesn't exist yet. For example, say that we again have ct_gfx called in this order:

1, 2, 32, 5

then calling freeimage(ct_img[3]) will result in an error complaining about how the first parameter is expected to be a number but got nil instead.

Now you can try to enclose the whole thing within an if statement, but it's more idiomatic to write

1

for id, img in pairs(ct_img) do
	freeimage(img)
	ct_img[id] = nil -- remember to remove old ids so we don't accidentally free the same resource twice.
end

Ah yes at the end of the loop you need to reset all the items in the array.
