When you save your JPEG in GIMP, expand the 'Advanced Options' when the 'Export as JPEG' dialog box comes up. Un-check the 'Progressive' box and then click 'Export'. Your JPEG is then readable in QGIS.
"Progressive" changes the encoding to display the image at increasingly higher quality levels until the image is fully loaded. QGIS is expecting standard encoding. Progressive encoding appears to be on by default in GIMP (at least in GIMP 2 - I can't remember for earlier versions).
Based on your comment, it sounds like you are adding each raster band separately, instead of the raster dataset. When you use the Add Data button and navigate to your jpg, don't double click on the jpg filename and select the individual bands, just select the file itself and click the Add button.
