Hej

Nu har jeg i lang tid siddet med grå hår og spekuleret på, hvorfor dette
lille program, der skal vise et indeks' billedefiler ikke virker. Programmet
nægter at tegne andet end nogle bestemte filer og kun fra bestemte indeks???
Hvis der er nogen der gider se koden igennem, og komme med forslag til
rettelser vil jeg blive meget glad.

Mvh Poul
