If you do not want to use the plugin's functionality (of displaying all images attached to the post) and do not want to use Flickr as a source of images, then the best thing to do would be to forget about WP-Juicebox and create and embed a Juicebox gallery independent of the plugin.
Try the following:
(1) Create a gallery with JuiceboxBuilder-Pro on your computer and save it to a new and empty folder named 'gallery_folder'.
(2) Upload the complete gallery folder to the root directory of your web space.
(3) Enter the following embedding code (without modification) into a 'Formatting -> Custom HTML' Gutenberg block.
<!--START JUICEBOX EMBED-->
<script src="/gallery_folder/jbcore/juicebox.js"></script>
<script>
new juicebox({
baseUrl: "/gallery_folder/",
containerId: "juicebox-container",
galleryWidth: "100%",
galleryHeight: "600",
backgroundColor: "#222222"
});
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->As you have WP-Juicebox installed, you can use the 'jbcore' folder from the plugin if you like (to avoid the need to upload the one inside the gallery folder). Just change the path in the following line to point towards the 'wp-juicebox/jbcore/juicebox.js' file inside the plugin's folder. (This is not necessary but will save a little space on your web server.)
<script src="/gallery_folder/jbcore/juicebox.js"></script>If you really want to, you can store your gallery images elsewhere (for example, your WordPress Media Library) but you'd need to adjust all the imageURL and thumbURL paths in your gallery's 'config.xml' file.
It would be much easier (and quicker) to just follow the three steps above. (No editing or modifications would be required.)
can't find my pro version...
Please fill in the Download Link Request Form and we'll send you a new download link for your Juicebox-Pro purchase. (I cannot find your transaction under the email address you use for the forum.)
It still shows up blank...
If you continue to experience difficulties, then please post the URL to your gallery's web page so that I can see the problem for myself.
Once I'm able to see your gallery live on your web server, I should hopefully be able to determine the exact cause of the problem and propose a solution.
Thank you.
