How to add some images to local cache?

[VoidVolker]

I have 5k/1Gb of images in Internet server. Client app PC have slow internet connection. I want to cache all this images at start and some other 7-15k small images in runtime. What is the simple way to do this? I tried to use node.js http.get(url) - but it's not very comfortable.

App: kiosk. OS: win7. Kiosk Internet: from 100kbit/s to 5 mbit/s.

Well browsers in general store a cache for all loaded images and use the cache if you request them again with the same url. So if that holds true with node-webkit(I haven't tested it) then you can just make a bunch of ajax requests to handle the creation of the cache.

I tried it already: after deleting container with images nw is clearing cache with this images. Loading images via js doesn't load them in cache.

I'm write my own cache system. Logic is simple:

1. Use special function in source code for images
2. It search image in cache and return local path.
   
3. If it not in local cache - it loads image from given url to local disk and return local path.

When application starts, it load catalogue with items and I call this function for each items picture. And do the same when update local catalogue. In my case there are >10k images @ >1,5Gb.
If image loads with error - it replace special error image "Sorry! Image not found".
