You appear to compare the vector bounding box which easily leads to misleading results in case of a rotated image. The only correct way is to compare point wise (eg true corner points of the image scene). Or generate a binary data/no data raster from a channel using r.mapcalc and then r.to.vect to make it a vector polygon truly circumscribing the image which can then be reprojected. Best Markus
