I assume you're trying to get a high res version from the system. In this case, I would go find the asset within the BLOX CMS asset management interface, and then go to the "other" tab to see information about the high res image.
From this screen, you can click to "view" the high res version, which will then open in a new window. From here, you can right-click and download it.
We only utilize web-optimized images on the front end of the website, so getting the high res is not available unless going through the admin.
Does this answer your question?
