@Jen, I think it is because we decreased the max size of pictures lately. They are limited to 256kB now. Do you have a way to take a screen shot on the computer? I use snagit to shrink picture sizes to almost nothing.
The reason for the shrinkage is: we are piling up media, and our hosting fees go up in tiers that include how much storage we use. So we need to use as little as possible 
I LOVE your recipe. I wil buy the ingredients and try it asap.
