As long as Qgis is set to "Project on the fly" (I think it may be
the default in newer versions), if you load the tiff file first, the
project CRS will be set to the one used by the TIFF file. If you
then load the CSV layer (use add delimited text layer) and in the
dialog specify the correct CRS for the the csv layer.<br>
<br>
If you really want to transform the tiff file, open it Qgis, then
right click on the layer and select Export->Save As and set the
CRS to the one you want used (same as the csv file) and save the
raster to a new file.<br>
<br>
Or use gdal_transform which was installed with qgis. You will need
to use the command line to do this <br>
