Rules are pretty simple for the photography forum.
1 - Only post up/link to images that you yourself have taken.
2 - Must be race car or slot car related.
3 - If the image is large, linking to it instead of embedding it is preferred.
Other than that, pretty simple.
I might do a general 'Awesome Racing Photo' thread just for linking to awesome photos that are freely available around the place, but other than that, please follow the rules :)
Cheers,
Rob.
