until not love.keyboard.isDown('left')

It sounds like you're trying to move an image when a key is held down. Using a 3rd party library timer is overly complicated for this.

You want to associate some X and Y variables with the image and draw the image using those variables. You can change them by using the love.keypressed callback or by checking for key presses in love.update if you want continuous movement.

Example:

function love.load()
    sprite = {x=0, y=0, image=love.graphics.newImage("test.jpg")}
    speed = 3
end

function love.update(dt)
    if love.keyboard.isDown("left")  then sprite.x = sprite.x - speed * dt end
    if love.keyboard.isDown("right") then sprite.x = sprite.x + speed * dt end
    if love.keyboard.isDown("up")    then sprite.y = sprite.y - speed * dt end
    if love.keyboard.isDown("down")  then sprite.y = sprite.y + speed * dt end
end

function love.draw()
    love.graphics.draw(sprite.image, sprite.x, sprite.y)
end
