There is something wrong with this raster dataset:

gdalwarp -r cubic -s_srs EPSG:32632 -t_srs EPSG:32632 ped208_cr.jpg ped208_cr.tif
Creating output file that is -2147483648P x 4898L.
ERROR 1: Attempt to create -2147483648x4898 dataset is illegal,sizes must be larger than zero.

Where did you get that rotated world file? For me it looks bad.
I tried to understand how rotated world files are created and how they should be interpreted just yesterday. Have a look at this mail on OpenJUMP-dev
http://article.gmane.org/gmane.comp.gis.jump.devel/14544
There is a small OpenOffice spreadsheet as an annex. You can play with the input parameters and look how the world file changes. Please report if you find that my logic was not correct.

hello,
I am very sorry, I have used this vlx under Autocad
http://www.cadstudio.cz/georefimg
to generate worldfiles

Old version jgw with
[GEOrefIMG command loaded. (C)2010, XANADU]
0.016719
201.172482
0
-0.016719
677613.094651
5142519.979935

New version jgw with
[GEOrefIMG command loaded. (C)2013, CAD Studio - www.cadstudio.cz]
-0.01559042361
-0.00603851412
-0.00603851412
0.01559042361
677613.0754770313
5142519.993070455

with the new version jgw working very fine into Qgis.
Sorry again
malcom jamal

PS
with ped208.jpg have a problem with re-size/re-sampling/rotating problem
with the same file converted before into PNG, and imported, no problem. Importing with Master version under Linux ped208.jpg have no problem.
