Good question! I couldn't find any limitations rather for length of shared text or size of shared images. But I think there are no real limitations out there. Maybe the share targets have the possibility to reject large files or long texts. This would mean that they will not show up in the dialog (maybe testing twitter with a long text would be interesting). But I think that there are no limitations.
But there could be the case, that maybe the share target will do something special with the text (truncating or whatever) or reduce the file size by reduce the quality.
I don't think that it is possible to find a preview generator. Anyways it couldn't be 100% correct, because the user agent/device has the power. But if you find one, let me know (I would be interested as well) :)
