Nice to see everyone try and help. As for images not loading. It can be a factor of your download speed. I use amber cutie at school and work and I average about 24mbps down, 4 mbps up. The slow image download can be a factor of your ISP (Internet Service Provider), Home Network (Are you doing other things on other computers or devices [Netflix, youtube, facebook, etc.]), and lastly device (Are you downloading images or videos at the same time, or maybe a torrent).
First I would suggest to do a speed check and see your speed, my 2 favorite sites are testmy.net, and speedtest.net.
This will let you know if your are having a slow connections. Also, if the connection is slow, then it may be the issue of the AmberCutie webserver timing your connection out.
If you have a decent connection (1mbps+), then you should look at your home connection, how many devices are on, and how many are currently being used at the same time. If you have a 1mbps connection and 3 computers on it, then you are overloading the line.
Lastly, if it is your device itself, then try to make sure that nothing else is going on. the best way to do that is to restart the computer, and see if that helps. make sure that no other programs are loading in the background
As for the AmberCutie site. If more users see this, than an investment into a CDN (Content Distrabution Network [http://en.wikipedia.org/wiki/Content_delivery_network]) May be needed.
Hope this helps
