I have had similar experiences with saver and phjuke. I have resolved all of the issues with some scripts and priority tweaking. I think the key was getting WebSaver to run at priority 1. I do not use RandomPic but rather use WebSaver, which loads a slideshow webpage that I created. I had the same sound skips when pictures changed while playing phjuke. What I have done is created this as my WebSaver.sh that is launched by saver.
# cat WebSaver.sh
sleep 4;slay -P 1 WebSaver &
First line slay's saver, which will stop saver from trying to relaunch WebSaver every 3 minutes. It also removes the need for FireKey(this my be fixed in the latest PicSaver.. it might be a good idea to try that app instead since I think it may be better).
The next line is funky but it worked for me.. there is probably a better way to do it. What it does is wait 4 seconds (enough time for the next line to run WebSaver) then sets the priorty of WebSaver to 1.
Start WebSaver. There is no "&" so the script remians running.. waiting for the WebSaver app to exit before continuing.
Last line restarts saver after WebSaver is stopped.
Get help, chat, and be merry..
