yep those buttons on the left take an age to load (relatively... Im only talking 5 to 6 secs, on broadband, but that may be too long).. tested on home connection, and its a slow as on the University of Warwick connection, so not just my connection..
Ive had a look and its the file sizes of those images.. the raptor pics are enormous at 128Kb.. they should be about 10-15kb ...whole page at 40Kb is what we used to reccommend to content providers (BBC etc)
If you run them through GIMP or photoshop and reduce the quality of the compression to about 75% or 80% I reckon the pic quality will be the same but youll save a whole load on file size.
