Before you show the first picture, scan the folder for JPEG file using
FindFirst, FindNext & FindClose (there's an example in the help). Fill a
TStringList with the file names, which can be alphabetically ordered or
not:
//First picture "|<"
Idx := 0;
load and display (MyStringList.Strings[Idx])
//"Next" picture ">"
Inc(Idx);
load and display (MyStringList.Strings[Idx])
//"Previous" picture "<"
Dec(Idx);
load and display (MyStringList.Strings[Idx])
//"Last" picture ">|"
Idx := MyStringList.Count-1;
load and display (MyStringList.Strings[Idx])
Good luck,
Ronaldo |
