image module - where is class "image thumbnail" defined?

Well, close to that. I actually want to try and change the theme of the image gallery. I noticed that the images in the gallery node has a class called "image thumbnail". I tried to define a class in my style sheet but no luck. Does CSS allow spaces?

Simply because the default does not use it, it does not mean its a bug :). Other themes might use it, still.

berub@penelope:~/repository/contributions-4-6/modules/image$ grep -n 'thumbnail' image.module
12:      return t('An image (with thumbnail). This is ideal for publishing photographs or screenshots.');
80:  $size_group .= form_item(NULL, theme('table', $header , $rows), t('Select various pixel dimensions, "thumbnail" and "preview" are required.'));
183:      if ($size['label'] && !in_array($size['label'], array('thumbnail', '_original'))) {
222:            $block['content'] = l(image_display($images[0], 'thumbnail'), 'node/'.$images[0]->nid, array(), NULL, NULL, FALSE, TRUE);
227:            $block['content'] = l(image_display($images[0], 'thumbnail'), 'node/'.$images[0]->nid, array(), NULL, NULL, FALSE, TRUE);
252:  if ($node->images['thumbnail']) {
253:    $output.= form_item(t('Thumbnail'), image_display($node, 'thumbnail'));
288:  $node->teaser = l(image_display($node, 'thumbnail'), 'node/'.$node->nid, array(), NULL, NULL, FALSE, TRUE) . $node->teaser;
303:  if (empty($node->images['thumbnail'])) {
304:    $node->images['thumbnail'] = $node->images['_original'];
366: * (e.g. image/view/25/thumbnail or image/view/14)
501:  // We'll add height to keep thumbnails lined up.
502:  $size = _image_get_dimensions('thumbnail');
511:      $content.= l(image_display($gallery->latest, 'thumbnail'), 'image/tid/'.$gallery->tid, array(), NULL, NULL, FALSE, TRUE);
533:      $content .= l(image_display($image, 'thumbnail'), 'node/'.$image->nid, array(), NULL, NULL, FALSE, TRUE);
649:  return variable_get('image_sizes', array(array('widt

In other words: its all over the place. But have a closer look at the function image_display().

In any case: if you want to chnage this behaviour, you should do so in yor theme. Read more on 'theme functions' for this.

Hi Bwooster47,

In case you haven't worked it out yet, I needed to change the layout of the thumbnails earlier and did it by...

1. go to your /modules/image/ folder and open image.css in a text or style sheet editor
2. add the following line to the end of image.css and edit accordingly.

.thumbnail img{ margin: .1em;padding-left:5px;padding-right:5px;padding-bottom:5px;padding-top:5px;background:white;border:1px solid #eaeaea;text-align:center;}

(the above style put a subtle, flickr.com-style, box around the mages)

Not sure if that's precisely what you were asking..but that did the trick for me. It gives me total control how thumbnails are displayed on the image gallery thumbnail pages.

There are some hard-coded styles in the image.module, such as the forced +75 pixel addition to the height of the thumbnails, but the style sheet should offer a lot of control for you.
