Normal texture drawn aufully - SLICK_UTIL + LWJGL

I just loaded a texture binded it and then drawn a cube with the texture. Here is the code:
t = texture
x,y = coordinates

	t.bind();
		glBegin(GL_QUADS);
			glTexCoord2f(0,0);
			glVertex2f(x,y);
			glTexCoord2f(1,0);
			glVertex2f(x + t.getImageWidth() ,y);
			glTexCoord2f(1,1);
			glVertex2f(x + t.getImageWidth() ,y + t.getImageHeight());
			glTexCoord2f(0,1);
			glVertex2f(x,y + t.getImageHeight());
		glEnd();

SO , take a look at the normal image:

And when drawing the image (modelview matrix )
there are some weird lines and resizing

Ideas?
