Adding galleries of photographs or other images to your webpages is a great way to display multiple pictures which are shown as thumbnails. When you click a thumbnail, the full-sized image appears in a pop-up window. Adding galleries is quite easy and is often the simplest way to add images to articles. Below is an example:
We use a component called Droppics (Components > Droppics) to help us add galleries of images to articles. We find that Droppics is easy to use but if you find that this option is not doing what you need, please contact us and we can soon fix it for your.
7.9.1 How many pictures per gallery?
Here’s a word of caution about the number of pictures in your gallery.
While galleries are super ways to display groups of images, if you add too many images to your gallery on any one particular page, you risk slowing down how quickly that page will load. Our experience tells us that if you have a gallery, it's best to have no more than 12 images in the gallery.
7.9.2 Gallery Image Sizes
Another word of caution about the actual size of the images that you add to your gallery!
Another factor which will affect how quickly your page will load is not only how many images you have in your gallery but also the physical size in megabytes of each image. Earlier in the section on Optimising Images we talked about resizing and optimising images before you upload them to your site. With Galleries this is a key point so we ask you to do your best and ALWAYS OPTIMISE before adding images to a gallery.
