Yes, we’re aware. Last few weekends the render service on Arena.net’s end of the API has been failing. Not much we can do about it unless there’s some way to inject a fallback URL for images into GW2 Armory.

One of the ideas for the site was to run its own tooltip system for guild wars 2 items, skills and traits. This has proven difficult to start and get our heads around, especially with the sheer amount of items listed under ‘/v2/items’, but it may soon be needed.

Developers are unsure when they can fix it and as a result, the issue won’t be fixed until they can work out what is causing it.
