product page image popup

[leedie]

Hello! Since i last worked with osc -- there is a new option on the product page at upload image. A small image upload and now an option for larger...but when clicked it asks for popup html -- I do not know what code it is asking for. I have larger image ready to use but is there something I need to add code-wise to popup? or will just uploading the image like I used to work?

 

Hope that makes sense and thank you so much for help. -A
