burning more than 4g

not sure if there is an easy way of doing this but i have around 20g of photos all sorted into various folders etc...
is there a way to select them all to burn and just pop in a new blank when required, instead of selecting what goes on each disc?

i've looked around toast but can't see the option to do this

thanks

I think if you just select the photos in iPhoto and then hit burn to cd/dvd it will continuously ask you for blanks until all images have been burnt...

thanks, managed to do it via toast, dragged it all to data disc and made sure it was set to mac only, if it's set to mac & pc compatible it won't do disc spanning?

Hmmm, that's weird.
But I suppose the hybrid disc format (UDF?) doesn't support spanning...
