Hi demonllama,
HD Quiz uses a custom image size for the image-as-answer images. This size is 400px X 400px.
This size can be easily changed by editing index.php located in /wp-content/plugins/hd-quiz/
Line 21 is add_image_size('hd_qu_size2', 400, 400, true); // image-as-answer
You can change the 400 to anything you want. The first 400 is the width, and the second 400 is the height.
Just note that you will need to either re-upload the images again to get WordPress to create new thumbnails or use a plugin such as Regenerate Thumbnails to automatically regenerate thumbnails for all images on your site.
Just please note that increasing the image size won’t be enough, as HD Quiz uses a maximum width of 600px. This means that your images can only really be a maximum of ~250px wide (larger images will automatically shrink down to fit the space). Because of this, you will need to set HD Quiz to allow for a wider container.
You’ll need to edit your themes’ CSS style.css to add the following rule.
.hdq_quiz {
max-width: 800px !important;
}
That above CSS snippet will change the maximum width from 600px to 800px. You can, of course, change 800px to any other size you want.
Lastly, since the CSS will be in your theme, you can add it and forget it. However, updating the index.php to change the thumbnail size will need to be done each time you update HD Quiz though since the update will rewrite the change to the default.
