The jpeg library needs to be available at build time of the Imager module. Adding it to the system later doesn't have any effect, unless the module has been built accordingly.  The build process only links against external libraries it can find during configuration.

(Just mentioning it, as it's not clear from your description whether you built Imager yourself, or where you got it from...)
