Hola. Como Estas?

two suggestions:

1_zoe, do you have any idea of how do you want to locate the a3/a4 pictures? maybe (just maybe, this is just brainstorming) it could be ok if the pictures could suggest the exterior itinerary like little "image tips". if that´s a linear thing it would be easier to appeal people or attract attention, so it would be impossible not to see them, since isolated spots are more improbable to get by and the size it´s kind of small.

so the idea could be 5 isolated spots for the really big pictures and a linear itinerary between them marked by the little ones. and when a certain time arrives maybe people can take them home (just the same at in i-95).

2_ i can draw a map in autocad for a flyer or whatever to suggest the itinerary(i have a madrid map autocad file)
