ImageDisplay Internal Error

[liwenna]

Hi Jordan,

Just to make sure (and because I generally like to state obivous
things...): you checked whether all the images are actually present?
This error most often occurs from files not being present and/or
filename-typoes.

A less obvious reason could be the 'macification' thing... don't know
how/what/why but bmp's created/modified on a mac can also give this
error. In that case simply opening and saving again with a windows
program (gimp, photoshop, might be paint even works) should solve your
problem.

best,

liw
