You should be using DOM for this.

PHP Code:

//find the row you want to atach the image to.
target_row = document.getElementById('target_rows_id');
img_col = document.createElement('td');
img_col.style.border = 0;

new_img = document.createElement('img');
new_img.setAttribute('src') = xoxo[choice];
new_img.style.align = 'right';
new_img.style.height = 253;
new_img.style.width = 486;
new_img.style.border = 0;

img_col.appendChild(new_img);
if(target_row.firstChild){
    target_row.removeChild(target_row.firstChild); //remove any prior image you set.
}
target_row.appendChild(img_col); 


Or better yet, just hard code the collumn and image in the html and give it an id attribute. then just swap out the image src.
