It comes back to asking your estate agent what, specifically, was wrong with the photos. Heaven only knows what he or she means by using a camera at "normal size" since digital cameras can take photos at a great many different resolutions.
Since this phone is in the Samsung Galaxy line I will bet two things:
- That the default resolution on the photos is such that the files are insanely huge.
- You might have taken them with the camera held in portrait orientation, and the estate agent wants landscape.
You need to ask him or her what it is they want, precisely. If they say something like, a JPG file, then you need to ask for more if that's what you sent them previously.
