I'm sorry - I should have been more explicit.  It is actually support for jpegs
that I am looking for as they are small in size compared to bitmaps which I don't
want to use. When you say that Free Pascal has support for jpeg what do you
actually mean?  Does it mean that I could display a jpeg from within the Forms

Many thanks for the reply.
