Flashing Keys when refreshing CiscoIPPhoneImageFile

When you have an image that needs constant reloading (using a refresh header), what happens on the phone is that your buttons you put in the CiscoIPPhoneImageFile go away whenever the image is being reloaded (replaced with one button: cancel).
Is there any way around that?

Can't think of any way to avoid that...

That's exactly the preliminary answer I gave the customer.
some food for thought: What about an update syntax for CiscoIPPhone* Elements? Using that, you could update just parts of an existing form. E.g. replace the picture without having to reload the CiscoIPPhoneImage XML elements (thus no button changes)? Alcatel-Lucent has that for their IPTouch series and it makes the whole video monitoring bit a lot more seamless (the phone will download the image, then when done replace the current image) and the whole thing is seamless for the user.
Alternatively.. once again.. apps on softkeys please (so we'd put the image in the background but at this point I'm not sure what kidn of frequency I could achieve with that.. to be tested).
