and album covers in the context menu.
Notes:
- This requires context_menu() to have a CSS selector that refers to the
<img> that we're operating on, otherwise we don't know how to find the
thumbnail, etc.
- Create Menu_Element_Ajax_Link which has an ajax_handler attribute
that contains a snippet of JS that we're going to run when the ajax
call returns.
- Add $.gallery_replace_image in gallery.common.js
- Add lib/gallery.ajax.js which can be used to ajaxify any link, and have
ui.init.js in the themes call that on all .gAjaxLink elements.
the "context" menu.
This new context menu is generated using the typical event processing
system, like our other menus. The specialized quick CSS and JS is now
gone, replaced by our generic menu handling code. It's all rolled
together currently using the thumb_menu UI for easy packaging. All
the CSS and JS is updated.
NOTE: the non-dialog links (rotate, album_cover) have a broken UI
because they return JSON which the quick.js code handled specially,
but we don't handle properly now. I need to fix this.
