Asking Price Sticker

This may be a stupid question, I want to edit the asking price sticker, I have read other posts, but I dont understand how to navigate to the sticker location, there is no file manager on word press so how to I get there?

This is what I have found on another post.

Edit the image using a photo editor like Fireworks or Photoshop to remove the ‘Asking Price’ section.The image can be found in /CT/templates/template_classifieds_theme/img/sticker.png then add this code in Design Setup >Custom Meta Data >Header Styles
