When I first joined this forum, I had no clue how to post a photo. Often, with a question being posed, there is a benefit to providing an image. This post addresses how I go about obtaining screenshots in Unity and in JNPG and ultimately, posting them. It is not the only way and I am surely not advertising for the products that I use to accomplish this goal but thought this might help some of our discussions on the board.
To obtain UNITY screenshots - 2 common methods for Windows users
#1 - PrtScn button - Open any image editing software and paste image, then crop and save as desired
#2 - (my favorite) - Snipping Tool - built in since Windows 7 - the reason I like it is that it bypasses the need to crop and open an image editing program - I do a New snip cropping my desired area of my screen and then click the disk icon and Save as into my Forum posts folder - efficient and simple (If you don't know where this is, click your Windows icon, search "Snipping Tool", right click and choose Pin to Taskbar - now, always present and ready for action)
To obtain a JNPG screenshot
In JNPG, depending on what you are trying to capture, you may want to hit F5 and "fly" to whatever location (using AWSD) and snap your photo. F12 for screenshot. You can take several and they will all show within the same directory. That file then moves into a location within Steam. The easiest way to retrieve it is close out of JNPG and your Steam Window should be open with your screenshot(s). You can then choose "Show on Disk" to be navigated to the file. I then cut it and paste into my Forum posts folder. The Steam menu looks as below.
How do I post my screenshot?
I use Imgur but imagine you can use any photo loading website. I like Imgur because the forum post code is easy to access and then paste into your post. Register with Imgur and upload your image. Click on your image and you will be shown your image and a menu on the right. Copy the entire BBCode with CTRL-C and paste into your forum post with CTRL-V. Your image will not immediately show but be only text. When you click Preview Post, you will be able to see your image.
Hope this helps. The forum is rocking these days. Don't want to invite bad karma but it has been fun without the negativity. K11 may chime in for you Apple-ites.
