Do you talk about TkPhotoImage objects?
If so, maybe, BLT extension makes it easier. 
However, BLT support on ruby-1.8.2 is very buggy and has no sample.
Please get latest BLT support libraries and samples from CVS. 
'ext/tk/sample/tkextlib/blt/winop1.rb' is an exapmple of 
image_resample (scaling), and 'ext/tk/sample/tkextlib/blt/winop2.rb' 
is an exapmple of image_rotate.
