There appears to be no way to delete the image file from the device from the search results screen. However, if you are seeing screen shot images in the search results that you couldn't find before, that's good, screen shot is working.

There are only so many places those screen shot files can be. My Z10 saves them to the camera folder (which seems to be the default location). I guess you said you looked there? (You also said you don't have a media card?) There is also a photos folder, and a download folder, which to me seem like the most likely alternate locations. Did you look in those?

I was hoping one could press and hold the image in search and then select properties and find the location, but alas properties isn't there. But still, you have confirmed the files are there, so you can eventually find them if you manually search using the file manager app on the device. And if you have a media card, look there as well. Once you find them with the file manager app you will be able to delete them.

Finally, if you are finding some screen shots you took but not others, restart the device and look again. Also, alternatively to searching on the device, you could use the computer with mass storage mode enabled on the device. At least I think you would need to enable mass storage mode, but maybe not.
