Replying to Images not showing anymore?

I've noticed lately that threads when I can easily view pictures from posters (ie: Typical College Girls thread) that the pictures aren't coming up anymore, are either some weird encoded and broken link, or the broken icon picture where I have to click it to view the picture. It just randomly started happening for almost every picture for me (usually its the broken attachment icon that i have to click) and I don't think it's my computer.

Sorry if this is noobish, I don't really care.
