Full Map Screen Capture

Is there anyway to copy a map image so it can be imported to a paint program to edit? I'd love to be able to grab one of my maps, put it into a flat image and resubmit it, it would allow me to save on space and lower loading times with less objects, and allow me to Photoshop out smaller details for a better game play I can screen cap one section at a time and put that together, but with larger images it's a lot of work. Not sure if there is a faster way, or if this is a possible feature to be added? Not sure, figure I should post somewhere to start looking for answers.

What you are doing is the suggested method. Alternately you could build the map in an outside program and then upload it to save space and load times.  

This is why I use MapTool to make my huge complicated maps. It has a feature that allows you to export the map as a single, flat image.

I often make my maps outside of Roll20 and put them together, but being able to make sure that everything lines up nicely, it's some times easier to quick build in R20 I haven't tried MapTool, but it may work. I like being able to grab set pieces from R20, easy enough to set layers, MT seems to have that, worth a shoot at least. More and more my maps are getting bigger and I was hoping to revise some older ones before I made everything flat, but that's a lot of copy and paste to gather everything together. Was mostly looking to R20 for a "full map capture and past" like I said, older maps get a little unruly, lots of zoom in and grab all images, I can Photoshop only so fast.   No hidden magic button I fear, but at least it seems like Print screen button may still be my best best.
