# Gallery images incorrect

 * Hi DeBaat
 * I’ve developed a site for a local photographer [http://www.countrysidephotography.org](http://www.countrysidephotography.org)
 * The photographer wanted something really, really easy to use: to upload images,
   categorise them and use the categories to create galleries and WP_MCM categorisation
   and shortcodes seemed perfect.
 * But there’s a snag: after the gallery is created a user can click on an image
   for a detailed view and then after that the previous / next to view images in
   the gallery. Unfortunately there seems to be no link between the gallery and 
   the original category and we are seeing random images from the media library 
   appearing.
 * Ideally I want to be able to restrict the images shown in the detailed gallery
   view to the ones that match the category of the current image.
 * Any ideas on how I find image categories?

 * Hai.
 * Looks like there is a misunderstanding between the terms category and gallery.
   
   A gallery is a way to group media files together and use that as some sort of
   shorthand for that group. A category is a different way to group media files 
   by assigning a category to each media file.
 * From the description above, it looks to me that you are using galleries by assigning
   categories.
 * The situation you would want can be created using the shortcode parameter “**
   alternative_shortcode**“. It works as follows:
 * Suppose you want to have a gallery with **ids=”20,18,19″**. Then you should create
   a MCM category, e.g. “**canada**” and assign these three media to that category.
   
   Then the post with the following shortcode for galleries:
 *     ```
       [gallery ids="20,18,19"]
       ```
   
 * should have the same result as the following using the category:
 *     ```
       [wp-mcm alternative_shortcode="gallery" category="canada"]
       ```
   
 * Hope this helps.

 * Thanks DeBAAT.
 * I tried [gallery ids="20,18,19"] and found the problem still existed: after clicking
   on one of the images and then next/previous I would eventually get images from
   outside the gallery.
 * I couldn’t get any output from [wp-mcm alternative_shortcode=”gallery” category
   =”canada”] but on the assumption it would replicate the same problem I did the
   following in my child theme functions.php
 * 1) add_filters to intercept the following:
    add_filter(‘next_image_link’, ‘my_next_image_link’,
   1, 2); add_filter(‘previous_image_link’, ‘my_previous_image_link’, 1, 2);
 * 2) add functions my_next_image_link (and previous) to allow a custom function
   my_adjacent_image_link which replaces the one in media.php
 * eg
 * function my_previous_image_link($size = ‘thumbnail’, $text = false) {
    my_adjacent_image_link(
   true, $size, $text);
 * 3) In this new function I check the category of adjacent images and if not the
   same as the original image then skip along the image array until a match is found.
 * Not really a problem of WP-MCM but it allows me to keep your fantastic image 
   categorisation system.
 * Thanks again
