No, you can't tell just from pics. There could be some indications, like a lighter body and longer snout could be more common in West German working lines, and a heavier, stockier body with a big blocky head might be more indicative of a Czech/DDR, but just in general. You can have Czech/DDR dogs that are lighter bodied, and you can have West German working line dogs that are heavy boned with big bear heads, so looks won't really tell you for sure.
If you have a pedigree for your girl, knowledgeable people can tell you what lines she is.
Is she or her parents on pedigree database?
