Heres how I do it.
Take a screen shot, ctrl, print screen key (just to rt of F12)
Open MS paint, then do ctrl/V, that puts your screen shot on paint.
Then you will crop from shreen shot what you want by:
On the paint page showing your screen shot click on the select down arrow on the top of the program and select rectangular selection. Then hold down (rt or lf) of mouse, place your cursor at the top left of area and drag a box to what you want to select. Then rt click and select copy.
Open another paint page and paste what was selected on this page (before pasting click the select down area and select rectangular election)
Then what you have pasted can be resized if necessary by selecting resize at the top of paint. Save to a file you can find when you have gotten what you want by clicking file/save as/JPEG Picture, name you screen shot when the pop-up appears and make sure it is going to the file you can find.
Now that you have your screen shot to post on the forum:
Go to https://postimages.org/ and select choose images and select the file you have saved then click open. Another page will open with the location of your image. From this page you can:
1. Copy and past URL from the hotlink for website line. This will have image html already included.
2. Or select information in the direct link line 2nd from top. For this url you copy you will need to add image html.
Thanks very much. I will give this procedure a test drive in the near future.
