According to my experience, reorienting an image is quite easy.
Use Check Reg button in the main SPM8 menu. You have then to select TWO images - a template and a real one, for example your structural image. A template can be found in the SPM folder, subfolder "canonical".
When TWO images are selected press "done".
Right-clock on YOUR image and select reorient > current image. Two important sings must appear. First a table with translation-rotation parameters, second - red line indicating relative contours of YOUR image on the top of the template.
Now play with the parameters. Change them manually until you see the maximum similarity of the orientation of main anatomica landmarks.
I do not change resize parameters.
After you finish apply the orientation to all the images of interest (your functional EPI images of the same session as your anatomical T1 image used for reorientation, and the anatomical image as well).
Hope this helps!
Good luck!
