You need to read the post again, and for comprehension.
He said;
Admittedly he never said Battlemap, but he said "maps with fog of war". And that pretty clearly is a battlemap. At least beyond a reasonable doubt.
No, that is simply not the case. I'm not trying to be pedantic here. There are, whether you believe it or not, many gamers that want the ability to display maps with fog or war, but not as a battlemap. Since some of those players may read this thread, I want to be clear about how I'm reading the OP and what my suggestion is.
First, I understand the word "battlemap" to be a map at a scale that you can play on. A common example in D&D and PF would be map with a grid of 1"x1" squares, where 1" = 5'. They can be pre-printed images, a dry/wet erase mat, or a digital image that you can move physical or digital miniatures, pogs, or counters on.
If you want to do this digitally, you will be well served by a VTT, which will give you additional features beyond displaying the battle maps, such fog of war, area of effect measurements, automatic resolution of damage and effects, etc.
But there are are also instances where you want to use fog of war for scales larger than the typical battlemap and outside of combat, such as for overland travel and dungeon exploration.
RealmWorks is one tool that allows for this.
So, we know you love RW. But he doesn't want to share campaign "content" that are text based. He specifically said he want to share images and maps with FoW. That's not what RW excels at. That what VTT's excel at.
The OP said, specifically: " I use it primarily for two things: to display images (of creatures/items/NPCs, etc), and to display maps with fog of war."
(1) "display maps with fog of war"
I've already address this above. This may mean he wants to use it as a battlemap, but he also mentions later in his post that he is displaying this on his laptop, so it doesn't seem to me that he is using it with minis or tokens or as a battlemap. It seems like he may be revealing the map as the party explores.
(2) "to display images (of creatures/items/NPC, etc)"
You did not address this. This is something RealmWorks excels at: displaying character portraits, location illustrations, diagrams of magic items, the runes the party sees on the door, and other things that you want to show the players without having to print out as paper handouts.
I have only a cursory familiarity with the major VTT products, so I do not know how useful they would be for this purpose in comparison.
