Thanks for your question and for the link to your screen shot; very helpful.
You can adapt either or both of the following suggestions for your application. The first suggestion gives a way to highlight the current tag in the cloud. The second gives a way to add the tag name to the gallery display.
First, the current tag cloud term has a special CSS class assigned to it. The default class name is mla_current_item, but you can change this by adding a current_item_class parameter to your [mla_tag_cloud] shortcode if needed.
You can use CSS styles in your theme stylesheet or inline to highlight the current item. Here is a shortcode you can adapt to your page for the cloud:
<style type='text/css'>
#mla-tag-cloud .mla_current_item {
color:#FF0000;
font-weight:bold}
</style>
<span id=mla-tag-cloud>
<strong>Tag Cloud</strong>
[mla_tag_cloud taxonomy=attachment_tag post_mime_type=image number=20 limit=5 orderby="random" current_item="{+request:current_item+}" mla_link_href="{+page_url+}?current_item={+term_id+}&tax_input{{+query:taxonomy+}}{}={+slug+}" mla_link_class="{+current_item_class+}"]
</span>
The inline styles are used to mark the “current term”, and the span tags around the cloud make sure the inline styles take priority over styles defined in your theme.
Second, to add the current tag name to your gallery display you can adapt the solution from this earlier topic:
Warning: array_key_exists()
The first post in that topic illustrates the idea. The [mla_tag_cloud] parameters add current_name={+name,url+} to each link in the cloud. The first [mla_gallery] shortcode just below the cloud uses post_mime_type="a-bad-type" to ensure an empty “gallery” and then uses the mla_nolink_text parameter to display a header with {+request:current_name+} to display the current tag.
I hope that gets you started on a solution for your application. I am marking this topic resolved, but please update it if you have any problems or further questions regarding the above suggestions. Thanks for your interest in the plugin.
