The error is an 'invalid type cast'.

That comes somewhere. If you run your app in lazarus, dou you get a call
stack when you get this exception ?
Nope, but I don't use a debugger in lazarus.
With this result, you might consider doing so, you could have found the
cause.
I just tried again and loading a png works, but loading a bmp fails. At least I
managed to produce a hopefully more meaningful backtrace:
(gdb) bt

#15 0x08154662 in TLAZREADERBMP__INTERNALREADBODY (this=0xb7f74090) at
intfgraphics.pas:4591

Some sources, intfgraphics.pas:4591 -> (3)
FImage := TheImage as TLazIntfImage;
1 + 2 + 3 ->
The class of TheImage is not a TLazIntfImage ! From your source, its a
TFPCustomImage.
TLazReaderBMP only supports TLazIntfImage, so derive your image from
TLazIntfImage or don't use TLazReaderBMP.
