ILBM 8/24bit bitmap save function

I'm looking for a fast help about saving a 24bit bitmap into an ilbm file.
I need to save also a special (non standard) chunk.

Until now I used old "saveilbm" function, present into NEWIFF package, based on iffparse.library.
It's ok for 8 bit screens but on 24bit ones fails, when I go to reload image I got a black screen.
It's tested on OS4 only so maybe it could be ok on OS3.

If someone can give some hit to find a fix for saveilbm function, or suggest another way to do that, it will be much appreciated.

My perfect solution is to have a full 8bit/24bit bitmaps working function like this
SavePic (struct ILBMInfo *ilbm, struct Chunk *ChunkList1, struct Chunk *ChunkList2, uin8 *FileName)

I thought also to switch code to datatypes but I really dont't know hot to write iff special chunks using picture.datatype.

I'm not an expert but I thought one needed to use IFF DEEP format for 24 bit images, ILBM could only do up to 8 bit images couldn't it? plus HAM.

ILBM handles 24/32 images and has done for quite some time.

@flash

ImageFX will save out 24bit ILBMs not so sure about inserting custom chunks though.

Likewise datatypes will too. MultiView(er) will save out 32bit ILBMs under OS4
