Image Cache broken (and solution)

[ghost]

Some sites like r18.com are not providing any caching headers for images so xbvr's imageproxy can't cache them.

As of right now, xbvr can't be used offline (disconnect internet and open xbvr in incognito tab, most images missing)

Also, why does the image cache even expire? It's not like images will ever be updated or changed. They should be permanent like stashapp, instead of sending 100s of unnecessary requests to web servers every time it's opened.

Even better would be to store the images in local files. That way they don't get lost if a scene is removed or the studio is gone in the future.
