You could try changing the SplashImage value in the config file to override the Standard Epicor one, and put the text in there, not perfect, but is should work… Note the file path appears to the case sensitive.
This image gets displayed immediately after you login.
Try this one as a sample… Unfortunately the version number of Epicor gets superimposed on the top.
I think the real dimensions of the image are supposed to be 540x310 pixels. If you mess up the value the standard Epicor splash screen shows.
Hope the helps. Other suggestion might be to hijack the Tips form.
