How to keep a figure on a defined page

[Hans B]

I always have the problem of my figures jumping a page forward or backward if I ad or remove some text, and by that creating a lot of secondary effect in the whole document. This is because the figure (or in my case a textbox with figure and caption) is linked to a certain line of text.
I would rather like to define that my figure stays on a certain page (and position) of my document, let's say page 3. Is there an option to do this?
thanks for any help, Hans
