Yes, it can be done, thanks to Dusky.
I don't know if this is what you like, but if you do, you have to put in the locations for your JPG in the script. And copy the script to your Haptek Skins folder.
Here is a script I know works with 2 pics:
#Haptek Version= 2.00 Name= breee3.hap HapType= script FileType= text
\clock [t= 0.0]loadbackground [file= data//standard//skins//j2.jpg]
\clock [t= 0.2]\loadbackground [file= data//standard//skins//j1.jpg]
\clock [t= 0.4]\loadbackground [file= data//standard//skins//j2.jpg]
\clock [t= 0.8]\loadbackground [file= data//standard//skins//j1.jpg]
\clock [t= 1.0]\load [file= data//standard//skins//Jukebox.hap]
you can change the location of your JPGS, as long as you change the directory command location. And you can change the timing, but it must increase on each line.
Kinda complicated, and I find it easier to change the background with hap scripts. I just drop the hap script into the haptek console, and the background changes automatically, without messing up the character.
I'll attach an example:
