There's no problem, that's how it's supposed to work.

All wiki pages are "cached" when you save them, so that a static html page is served for every page view instead of having to regenerate them from wikitext every time.

DPL has an extra level of caching available, which you're hopefully using (I haven't checked), which means that it might not even change the DPL output when you edit. (And that's okay in many cases.)

If you want the image to change randomly on every page view, I recommend using javascript to do so. (That's what I do.)

edit: BTW, I know you probably just set it to this to test, but "dplcacheperiod = 1" is not a good idea. DPL can be used for random content, but is not intended to generate random content on every page view, and should not be used in that way as it is very server-intensive, and if DPL uses too much server resources, Wikia Staff may decide to turn it off completely
