testo scorrevole tipo marquee modificato

[manu89ft]

ciao ragazzi, sto cercando uno script che mi permetta di avere del testo scorrevole, nel mio caso una serie di piccoli loghi, scorrevole con funzionalità come il marquee (deprecato) solo che ad esempio quando vado sulla sinistra della banda essa inizia a spostarsi verso sinistra se verso destra va verso destra, praticamente in base a dove vado il mouse può cambiare il senso con cui gira.. Sapete aiutarmi?? grazie

Il codice è questo di uno script che ho trovato però delle volte si imballa o non riesce a farmi scorrere tutte le immagini.. ma ci vogliono le librerire prototype per farlo andare?

[manu89ft]

è molto strana come cosa, se io lo faccio girare in locale non mi da problemi, mentre quanto lo messo online oltre a vedersi il caricamento (è bloccato per un attimo, ma questo è normale) dopo un certo tempo delle volte capita che si crei una riga sotto con dei loghi fissi, praticamente una riga scorrevole e sotto 2/3/4 loghi fissi, capita solo delle volte.. Sembra quasi che lo script vada in timeout non so, che raggiunto un certo tempo non si carica più i loghi nella parte scorrevole ma li lascia li fissi.. avete qualche idea?

[manu89ft]

conoscete qualche buono script crossbrowser che simuli un marquee continuo e che sia abbastanza leggero?... help

[manu89ft]

tutti i testi scorrevoli mi danno problemi o rallentamenti vistosi.. non e' possibile mi toccherà farlo in flash
