Thanks guys for all your help!

If you are using LibTIFF, just compile with JPEG support on,

erm, this is done by....

I mean I've set all the flags in the tiff file for COMPRESSION (7), and JPEGCOLORMODE (RGB) and JPEGQUALITY(75) etc but it won't open or display. Do I have to explicitly turn jpeg support 'on' somewhere....

Does the call to TIFFWriteEncodedTile() actually compress the data and then write the tile to the tiff file automatically? I have set the IJG stuff up to compress data (y'know, the jpeg_compress_struct and error_mgr etc) but do I need to do this and then tell the TIFFWriteEncodedTile() function to just write the already compressed data from the buffer?

Also ImageMagick looks cracking! Thanks!
