To add an image block to a Nucleus Card, begin by dragging and dropping the image block onto your Card timeline.

Upon adding an image block to your Card, you'll be presented with an upload screen where you choose which image you want to upload and insert into your Card.

NOTE: To successfully upload an image, your image's file size must be 2MB or less. If your image is larger than this, use a free online image compressor like or to shrink the overall size of your image. By limiting the allowable size of image files in your Nucleus, we can keep the site speed of your Nucleus faster and thus improve usability as well as search engine friendliness.


Add a caption to your image by using the caption field in your image card block settings.


Add a direct link to your image. This will make your image clickable and when a user clicks on the image, they will be directed to a URL of your choosing.

By default, when a visitor to your Nucleus clicks on an image with a link, the visitor will visit that link within their existing tab.

If, however, you want to direct the visitor to a new tab upon clicking the image, simply toggle on the setting that reads 'Open link in a new window.'


Adjust the size of your image using the slider. Drag and move the slider until the image is your desired size.


Realign your image to the left, right, or center of your Card using the alignment options.
