WordPress already comes with basic features to manage your image uploads. You can add alt text, caption, and description for images and perform basic crops. Media Library Assistant comes with a bunch of useful shortcodes to display a tag cloud, media list, and gallery on your site. It also has an advanced search box to make your life easier.
This plugin lets you assign IPTC, EXIF, XMP and PDF metadata to your WordPress fields. Bulk and Quick edit actions are available for the common and custom fields. Media Library Assistant plays well with Photonic Gallery, Jetpack, and other popular plugins.
Media Library Assistant’s shortcodes do have many parameters, so you will want to do your homework to set them up properly. This is a free plugin.
