Never seen this before, so I only can guess.

First of all, I don't know what version of TIB_JPEGImage
and package you are using, so at first I would ensure
that you use the following distribution.
http://www.iblogmanager.com/download/misc/IBOTST.zip

Open the *_D6 project group and build all packages. Within
the project group double-click the design-time package
IBOTSTDT_D6 and click "Install".

Though, your error is more likely that it is used an old
version of dsgnintf.pas behind your scenes. Do you have
an older Delphi version installed? Perhaps one of your
library path in D6 is pointing to an old dsgnintf.pas?
