My first guess is that your Qt application can't find the proper plugins 
for image formats. So either you should use png pixmaps (which are 
directly supported) or you deploy the plugin for the image format you 
are using.

For example, if you are using JPEG images you should make sure that the file
<here-resides-qt>\plugins\imageformats\qjpeg4.dll
is available on your device in a subdir named imageformats below your 
application directory:
\Program Files\ManojsApp\imageformats\qjpeg4.dll

In the final Qt/WinCE 4.4.0 release we will provide a comfortable way to 
deploy Qt plugins. At the moment you have to add something like this to 
your .pro file:

wince*: {
     pluginFiles.sources = <here-resides-qt>\plugins\imageformats\qjpeg4.dll
     pluginFiles.path    = \Program Files\ManojsApp\imageformats
     DEPLOYMENT += pluginFiles
}

Hint: in debug mode the plugin names have a 'd' added to their name 
(qjpegd4.dll, qgifd4.dll, ...).
