Hi R.e.

Thank for your advices, now I'll try to do my .gifs, crisper than before, and I'll check typefaces , I don't remember what kind font I've used.

I put my suggestions about Safari and Firefox, only because I tested my site with both of these browser, because I don't have IE, and the first release of it, dosen't work well on IE, now if you check it and it works well I'll erase my suggestion

Best

Stefano
