Feel like the Emotos you chose were not the best fit for your business. There's no need to worry, you can always change them.
Option 1: Once you have selected the emotos and gone to the next page, you can always click on the back button and change them.
Option 2: If you have reached the last step, just before posting, you will find an option to ‘Change emotos’. You can click on it to be directed to the emotos page.
