Cutting the text without using summary

Hi,

I have to set my rss feed to full in order to get my images to show. Doing that, however, basically makes it so that readers don’t even need to visit my site and that just isn’t going to work. I need to be able to stop the text at some point so that they have to click through to read the rest. The more tag used to do this, but I hear that it’s been “fixed” and that it now doesn’t perform that function. As I said, I can’t set the feed to summary because then the images don’t show up. Can anyone offer tips on how to cut the text?
