In order to make an image a slider in Squarespace, you will need to first create a new page or post. Once you have done this, click on the “Insert Image” icon in the editor toolbar.
This will bring up a dialog box where you can select the image you wish to insert. Once you have selected your image, click on the “Add to post” button.
Once the image has been added to your post, you will need to click on the “Image” icon in the editor toolbar. This will open the image editing menu.
In the image editing menu, you will need to select the “Slideshow” option. This will turn your image into a slider.
You can then use the arrows in the image editing menu to add additional images to your slider. Once you are finished, click on the “Update” button.
Your slider is now complete!
