You can enable the alt attribute for the image fields and that should
handle that.
You should probably use css to style the image and not attach a style
attribute to the img tag

Hi,
I recently needed to insert an image from an image field into the node's body
prior to rendering. I was able to do this using this code:
function THEME_preprocess_field(&$vars) {
if ($vars['element']['#object']->type == 'case_study'&&
$vars['element']['#field_name'] == 'body') {
$node = node_load($vars['element']['#object']->nid);
$img = field_get_items('node', $node, 'field_cs_image');
$img = field_view_value('node', $node, 'field_cs_image', $img[0], array(
'type' => 'image',
'settings' => array(
'image_style' => 'list_image_large',
)
));
$img = render($img);
$vars['items'][0]['#markup'] = str_replace('alt=""', 'style="float:right;margin:0 0 20px
20px" alt="' . $node->title . '"', $img) . $vars['items'][0]['#markup'];
}
}
I don't like having to use the str_replace() function to specify attributes for
the image but my efforts to use theme('image', ...) and theme('image_style',
...) were unsuccessful because they don't include width and height attributes.
I saw the big thread with Dave Reid on the performance issue with getsize(). I
understand the reasoning for removing the function but how is it that rendering
the image with field_view_value() produces an image tag with width and height
attributes? Couldn't the theme functions use the same method?
Is there a better or more proper way to render an image with width and height
attributes AND specify other attributes such as alt and style?
Thanks,
Cameron
