Do you mean that you get link errors?
Anyhow, if you do things with images, you are normally better of
to use the wxImage class. Images are platform and format independent
while bitmaps uses a highly plarform dependent representation and using
bitmapCreate is therefore not recommended.

The best way to do this in the current version of wxHaskell is to
write to file indeed, and to read from the file using imageCreateFromFile.
In a future wxHaskell, I will add support for the wxHTTP class, and the
wxInputStream's. Using that, you will be able to read a (JPEG) image
directly from an HTTP inputstream.
I hope this helps,
