It's really not rocket science. The pics are in "C:\ProgramData\Vectric\Aspire\V9.5\BitmapTextures\1_Wood". Just use any good paint program, I used Corel Paint, rotate the image 90 degrees and save as a different name. I just added a "VG" for vertical grain and "HG" for horizontal grain to the end of the filename. If you want to keep the custom changes separate, put them in the folder "C:\Users\Public\Documents\Vectric Files\Material Images" and they will appear at the top of the list in Aspire/V-Carve.
