Can't convert psd to jpg

[Guidance]

I'm trying v4.10 (the one at download page marked 4.11 is actual still 4.10):

> nconvert -rmeta -gamma 1.5 -quiet -q 60 -opthuff -ratio -rflag decr -rtype linear -o d:\g\_thumbnail\3397.jpg -truecolors -resize 128 -out jpeg "D:\g\pictures\Upload\Pics\photo.psd"

Error: Can't open file (jpeg)

Error: This output isn't possible (not yet implemented) (D:\g\pictures\Upload\
Pics\photo.psd)


I'm wondering since xnview can view psd, why nconvert doesn't work?

If I interpret the error messages of Nconvert right, Nconvert doesn't understand your command line parameters in the intended way. It interprets "jpeg" to be an input file and "photo.psd" to be the output file.

I have tried to change the command line so that it works properly, but my current Nconvert knowledge isn't sufficient (still learning). Hope this info helps anyway...

After changed the option order, i.e., strictly follow the order with the help, it works!
