<p>Generic rules for raster image files is there will be at least
two or three files for each tile:</p>
<p>* The raster itself</p>
<p>* The world file which has a similar extension usually ending
with a W e.g. JGW for a JPEG tile</p>
<p>* One or more XML files</p>
<p>The world file contains the coordinates and pixel size
information, the XML file(s) will contain the CRS information.</p>
<p>If these files are missing Qgis will display a ? at the end of
the file name when attempting to load it.</p>
<p>You can set the CRS in Qgis to compensate for a missing XML file
CRS, but the world file is essential otherwise the raster will be
loaded at the origin coordinates (0,0) of whatever CRS is being
used.<br>

feel a fool now, but I am struggling to get QGIS 2.18.28
to upload the files in the Raster (miscellaneous) section
as I used to do. I just get all the files not being
recognised.</span></p>
