    15 = Responsive Portfolio Image Gallery =
    16 
    17 Portfolio Gallery is a powerful, lightweight, filterable, and responsive image/photo gallery plugin. The aim is to showcase your images/photos in a much more professional way. Using WordPress Post Editor, you can create as many portfolios as you like. There is a powerful settings tool in the plugin. By using portfolio settings, you can select the portfolio categories of your choice, you can set the description length, the number of portfolios to show, hover and filter effect, and lots more...
    18 
    19 The portfolio plugin represents image thumbnails using many CSS3 hover and filter effects. By clicking on a thumbnail, it will expand a preview box and display a larger image of that thumbnail. Also, show more carousel images related to the displayed portfolio! It will also feature some other content like titles, descriptions, and link buttons. Using a simple SHORTCODE on different posts or pages, you can showcase your portfolios in a smart way.

     81== Frequently Asked Questions ==
     82
     83= How do I create a portfolio gallery? =
     84Create portfolio items under the Portfolio post type by assigning them to appropriate categories and setting featured images. After that, go to the `Generate Portfolio` section from the admin menu. There, you can create a new gallery by including the categories you want to display. Once generated, use the `[shortcode]` from the right sidebar on any post or page to showcase your gallery.
     85
     86= How do I display the gallery on a page? =
     87Use the `[shortcode]` provided by the plugin. Example: `[rpgal-gallery]`. The free version supports one gallery per page.
     88
     89= Can I add multiple categories to a portfolio item? =
     90In the free version, each portfolio can be assigned to only **one category**. For multiple categories per portfolio, please upgrade to the Pro version.
     91
     92= Do I need to set featured images for portfolio items? =
     93Yes. The featured image is used to generate the thumbnail for each portfolio item. Without a featured image, it won’t appear in the gallery.
     94
     95= How do I customize the hover and filter effects? =
     96Go to the `Generate Portfolio >> Advance Settings` page. You’ll find options for selecting different hover effects, filter styles, direction, and animation types.
     97
     98= Is it possible to hide the portfolio description or carousel? =
     99Yes. You can hide both the description and the carousel from the settings panel in the admin area.
     100
     101= Can I add custom CSS to style my gallery? =
     102Absolutely. There’s a Custom CSS box in the settings where you can add your own styles. Your CSS will override the default plugin styles.
     103
     104= Why aren’t my galleries showing after updating? =
     105Please make sure to include the portfolio categories (instead of excluding them, as in earlier versions). This change was introduced in version 1.1.
     106
     107= How do I add buttons in the preview section? =
     108In the free version, each portfolio supports a default button with text and link. In the Pro version, you can add unlimited buttons with custom labels, links, and open in new tab options.
     109
     110= Is this plugin compatible with the latest WordPress version? =
     111Yes. The plugin is regularly tested and updated to maintain full compatibility with the latest versions of WordPress.
     112
     113== Migration Notes for Version 1.3 ==
     114
     115**Version 1.3** is a major update with internal changes that may affect users upgrading from older versions. We've made structural improvements for better performance and flexibility, which means certain elements have been renamed or migrated.
     116
     117**Don't worry - most changes are applied automatically through the version checker method.**
     118
     119However, please visit `Portfolio → Guide` in your WordPress dashboard for detailed upgrade instructions.
     120
     121=== What You Should Do ===
     122
     123- ✅ **Shortcodes**: Go to the pages/posts where you added `[rcpig-gallery]` and replace them with `[rpgal-gallery]`.
     124- ✅ **Post Type Visibility**: If your portfolios are missing, go to your dashboard > Portfolios, and ensure items are listed under the new `rpgal` post type.
     125- ✅ **Check Gallery Settings**: Visit the `Generate Portfolio` section to confirm your included categories are set correctly.
     126- ✅ **Custom Button Data**: If you previously used buttons in your preview, confirm that they appear as expected. If not, re-enter them using the new fields.
     127
     128We’ve tried to make this transition as seamless as possible. However, if you notice anything missing or broken, re-saving your portfolio settings or re-adding buttons under the new structure usually resolves the issue. If you need help, you can contact us at anytime.
     129
     130== Upgrade Notice ==
     131
     132= 1.3 =
     133This is a major update with a fully redesigned admin UI, enhanced security, bug fixes, and improved compatibility. A new "Plain Text" preview mode is added, and older plugin options and post meta are migrated automatically. Please back up your site before upgrading.
    118134
