Also, you shouldn't be using someone else's wireless network unless they have given you permission, even if the name is 'free public wifi'.
And for the no pictures problem... Well, it seems odd. Maybe the wireless router is blocking certain file extensions.

The program in Windows XP used for finding wireless Internet access shows two kinds of connections -- access points, which let you jack in to the Internet, and ad hoc networks, which provide access to a standalone computer.
The Windows icons for these two are different. An access point is designated by an antenna; an ad hoc network looks like two notebook computers side by side.
Generally, you want to avoid ad hoc networks in public places. At best, they're a radio signal to nowhere; at worst, they could be someone looking for a vulnerable PC to compromise.
The "Free Public WiFi" connections I was seeing were all ad hoc networks. Just out of curiosity, I connected to one once. Nothing happened.
When Windows connects to a network, it retains that network's name, or SSID, then broadcasts its as an ad hoc network, essentially inviting a connection. You can find more details here. Microsoft has said it will fix this in the next XP service pack; it's unclear if Windows Vista behaves this way.
