Hi Kye,
Wow! I don't know how you find these things so efficiently, well done!
And thank-you for the heads-up on the gasket set, it has now arrived safely.
We had that exact mower can when I was young.
If your photos are on a camera/PC (like me) I can help, but if they're on your phone that can be more difficult as they're all different. The phone often tries to detect which way is up, this works for straight horizontal/vertical but hold it at a diagonal angle and it can get confused. There may be an 'auto-rotate' option to turn on/off. These will generally only do 90� increments. Otherwise you may need (or have) a simple photo editor built in that you can use to force a rotation (and cropping) before uploading.
The Lauson one's pretty straight.
I tend to download my photos to a PC, crop, rotate (often by 1-3�) and reduce them before uploading. Tedious, but allows those strange 60's-movies-type angles to be corrected!
Cheers,
