How to change the picture of a page?

Is there a way to change the picture of a page in the page tab to the view of the whole map? If I put a full map as a png/jpeg etc. it keeps it as the image, but if I build one from scratch, I always get the image at the bottom of the map layer I think. Im, aware that I could do a print screen and then crop the map and insert it so that it becomes the image but it's way too much time consuming.

Hehe. i've been wondering what controls that thumbnail picture too. Didn't know it was the "bottom" image, if that's it. Mine seem to change periodically. I add new pictures on my map pages frequently during the game, and sometimes I look up and the Page icon is one of the newer pictures. It's a bit odd, but kind of nice that it makes an automatic thumbnail instead of needing to set one each time. Would be nice if you could re-set or change it if needed though, or Lock it to a certain icon so it doesn't keep changing.

From what I have seen in building maps, it appears to be the largest image that you have on the map layer. I will often find the image that I want to be the thumbnail. Set it's dimensions to be the largest of any thing on the map and push it to the back behind everything else.

Thanks I wasnt sure how it determined which image to take.

Yes, the thumbnail uses the largest image on the map, although I believe it goes by the image's native dimensions, not the dimensions you've scaled it to.

i have wondered about this one scene has decided to use a bench as the thumbnail. others have picked minor props as well. i try to put any non current scenes into the archive so i can quickly switch scenes.

An option to right click an image on the map layer and 'make thumbnail' would be pretty awesome. I guess i ignore the images, and just read the words and archive 95% of my stuff, but a relevent thumb nail (visible on the archive!) would be super helpful.
