Not only for Lynx: in fact you are designing for accessibility. Consider
- the blind user, with his speech synth trying to make sense of your cute imagemap.
- the bandwidth-poor user (my little students, behind a modem, with a sucky ISP, in Mexico), that prefers to navigate with images off.
- people with a small screen, that would prefer frames not to be vital.
Keep on doing the right thing. Bask in the approval of
