I am building a Nextgen branding for North America and it is coming along nicely however I have a small problem and I do not know how to fix it.

My icons(BMPs) are combined in single files of about 20 icons each. I can display the pois with the right icons on the map but if I click on a specific poi to get the details, The detail screen display the first icon of the strip, not the same icon as displayed on the map.

Do you know how to fix this?

An alternative would be to split the strips in individual files but I am trying to avoid having about 400 to 500 small files.
