Simple widget for displaying images from the Media Library with plenty of configurable options.
For the time being, galleries that use the ids parameter (similar to the already-existing include parameter) will not influence the widget unless you copy-paste the list of IDs and use the Attachment IDs option. Old style galleries that would just use the
[gallery] shortcode will work as expected, as will images attached/uploaded to a post. This has to do with how attachments work in WordPress, which is the basis for this plugin. New-style galleries no longer depend on attachments to a specific post.
This widget can only grab images that were uploaded into your Media Library. See the WordPress Codex for more information.
The image is probably not associated with a post or page and will default to linking to the file if a link option is chosen. To associate (attach) an image with a post or page, go to your Media Library and click on the Unattached link next to the item to choose a post to attach it to. See the WordPress Codex for more information. The link behavior can be altered via filter.
The easiest way is to mouseover or click an edit link for the post or page in question. The ID number will appear in the URL; e.g.
http://yoursite.com/wp-admin/post.php?post=41&action=edit indicates that the ID of the post or page you want to reference is 41.
The anchor link relies on the ID that WordPress automatically generates when you insert an image with a caption. If you inserted the image manually or without a caption, the anchor won't jump you to the spot in the page. The ability to specify an anchor may be added at a later time, or you can just add the ID (attachment_##) to the img tag.
The images may be missing the thumbnails of that size and by default will pull the full size image instead. Try using Viper007Bond's fantastic Regenerate Thumbnails plugin to create new versions for any new or changed image sizes.
