As a Roblox Developer, it is currently impossible to localize the images and title/description of gamepasses / badges, and the images of
icons (implemented) / thumbnails (implemented). This means that everyone, regardless of whether they speak English or not, sees the gamepass, badge, icon and thumbnail images and text in English.
Roblox should allow users to upload multiple images to gamepass, badges,
icons (implemented) and thumbnails (implemented) (so that the text on these images can be localized), they will then be able to set each one to a different language which will be seen by a user if they have their language settings set to that language. The same will happen for titles/descriptions of these assets. This would work similarly to how we can already do this for game titles and game descriptions.
If Roblox is able to address this, it will be beneficial to both developers and players, because it will allow users which don’t speak English as their first language to understand a gamepass or badge if it has any text, and might therefore be more eager to purchase the game passes, obtain the badges or play the game.
