So, I read that using gets around the 10MB limit. Does this mean I'll be able to load more images without issue?

Or should I dig into the on first download thing?

My app is to teach CDL students how to do pre trip and I'll be using 100+ images when it's all said and done.

There is a 30MB limit. And if that isn't sufficient:

... and with the limit is 50 MB.
