From your Design Tab, choose Content.
To change the Annual Catalog you will need to change both the image and the location of the catalog. If you click the pencil it will open up the code. you will see this:
< a href="http://su-media.s3.amazonaws.com/media/catalogs/NA/20130601_AC_en-CA/20130601_AC_en-CA.pdf" target="_blank"><img src="http://i477.photobucket.com/albums/rr133/DebbisDesign/Catalog_zps73e54837.jpg" border="0" alt=" photo Catalog_zps73e54837.jpg"/></a >
In this code the Red section is the location that the PDF file is stored. Just open the file through the SU, copy the URL and paste it in here, making sure that the " " are left at the beginning and at the end.
The Purple section is where the catalog image is stored. There are 2 ways to get the image here.
1.)Save the image to your computer, upload it somewhere and then post that link here.
2.) The other way would be to hover over the image, click with the right mouse button and open image in new tab. Then open that tab, copy the URL and paste it in the purple section here. Again, you must make sure to keep the " " intact.
To add a new catalog: Still in your Design/Content Tab- Categories-Widget, Module-Embed your own HTML, Click the Add Module Button. A box will open. Title it the name of the Catalog so it is easy to find for editing later. Copy and paste the above HTML code, change the red and purple code to fit the new catalog. Click OK. You will need to drag it to the location you want it. It will automatically be put in the top left hand column.
