Cache images

Hi,
I'm kind of new to web developing in general and caching in praticular, and I have a question regarding caching.

I use php to build web pages dynamically. These pages contain static images which appear in all of my pages (logo, menu, footer).
Is it possible (and how do I do it if so) to "force" all the static images to be cached, and still get the dynamic text "fresh" every time (most of the text is read from a database, which is constantly updated)?

After doing a lot of reading, I got to the point where I think that sending an "Expires" http header with a date far in the future should solve this, but I don't
know if it really solves the problem (by the way, how can I check to see if the images are sent from the server or fetched from the temporary internet files folder stored
on the local computer?).

p.s. - I don't know if this matters or not, but all of my pages use the same template (which has all the static images). I concatenate all the html that I want to show in
the main section of the page (after building it according to the data read from the database) into a variable and include the template file, in which I put the
variable in it's position. No frames are used in the template.

Thanks in advance,

Topatidle
