. between 320px , 462px want remove picture , have links showing. want text links come alt attribute. know can text this:

var $alttext = $('img').attr('alt');

and think can use 

$("img").removeclass("image");

to remove images

what cannot figure out how put text between , it's

<li><a href="img/1964_gto.jpg">1964 pontiac gto</a></li>

i cannot figure out how have apply in particular media query.

use 

$("a").each(function(i){     var img = $(this).find("img");     $(this).text(img.attr("alt")); });
