PPM Parser

I try hard to avoid asking for help here, but I just can't figure this shit out.

I need to write a PPM Parser for a CS class and I am having trouble writing the image data.

It seems to read it fine, but when I write a file it writes the image 3 times on the top row.

Here is the code:

I left out the header file.

Here is the output

Thanks for any help.
