I just installed Open Cart via Softaculous and am trying to edit the stock images such as the homepage logo, banners, catalog items, etc. but I have no idea where these images are located in the code. Is there a way to use a tool like the Google Developers Tool (in Chrome) or Dreamweaver to determine the code location so that I can edit it with a text editor? Or does one have to learn the schematic "map" of the code in the given open-source template to effectively change code correctly in the website??
