Parametric kills you in terms of stretch factor. I almost never use it with photo textures unless the photo is close to the size and shape of the object. I typcally start with Object Cubic. It gives me scaling control along all three axis. The quick fix for tiling a photo texture (I don't have time to do a pic for this at the moment but)... if this is your picture with edges A and B: A------B Go to your image editor and make a duplicate, flip it and align the two images thus: A------B B------A That show repeat but not a disrupted tile on the horizontal axis. If you next make a copy of the pair, flip it upside down and move the new "flipped pair" above the original pair...it tiles vertically as well. Again, you'll still see repeats, but not the obvious seams.
