hi,

how can i detect the format of an image file, if it can't be derived
from the extension.
(i get a blob file out of an oracle database).

i want to save the binary data i get from the database through a query,
to a file with the
proper extension (gif, jpg, etc.)

the picture formats i want to detect are:
tiff, gif, pcx, bmp, tga, jpg (and more if possible)

and maybe this is possible for other binary data files (like avi's,
wav's?)

many thanks in advance,

greetz,

vincent
