Don't use QString but QFileInfo for this. There's the corresponding API to work with file extensions.

but we if have to incliue a extra header file , will no increase the executable size

if you insist on it, there are still the standart QString functions
splitRef & rightRef and char wise comparing.

How do you figure this? There's no relation between headers of non-template classes (except for the ones containing inline functions) and binary size.

just use

QString s;
bool endsWithpng = false;
endsWithpng = s.endsWith("png",Qt::CaseInsensitive);
