so if you place a debug point here:
private static final long serialVersionUID = 403L;
public String[] getImageName(String category) {
File photo = new File("src/com/webphotogallery/public/
wpgimg/album/"
+ category);
//File photo = new File("wpgimg/album/" + category);
String[] photoList = photo.list();
return photoList; <<<<<<<< DEBUG
}
Does the new image appear in the photoList array?
