QPixmap::QPixmap ( const QString & fileName, const char * format = 0, Qt::ImageConversionFlags flags = Qt::AutoColor )

Constructs a pixmap from the file with the given fileName. If the file does not exist or is of an unknown format, the pixmap becomes a null pixmap.

The loader attempts to read the pixmap using the specified format. If the format is not specified (which is the default), the loader probes the file for a header to guess the file format.

The file name can either refer to an actual file on disk or to one of the application's embedded resources. See the Resource System overview for details on how to embed images and other resource files in the application's executable.

If the image needs to be modified to fit in a lower-resolution result (e.g. converting from 32-bit to 8-bit), use the flags to control the conversion.

The fileName, format and flags parameters are passed on to load(). This means that the data in fileName is not compiled into the binary. If fileName contains a relative path (e.g. the filename only) the relevant file must be found relative to the runtime working directory.
I evidently didn't place it in the runtime folder? I was attempting to use the directory i use for my image resource file, is it possible to use that? or do I have to copy the folder over at runtime to test? Also is it possible to replace pixmaps placed using QtCreator by label name, such as my fire button switching from place during different modes of the game? could i use a boolean check slot /signal connection like this (after the boolean condition check) ui->F_43->setCellPixmap(4,3,fire);
