OK, cate-we're getting this done. I've been trying to guess where you're getting in trouble and I think from your "I got it!" post it's in saving the picture. Follow the numbers.....
1. With scorecard showing hit PRTSC (your print screen button.)
2. Open Paint and Paste the image.
3. Use the cropping tool to surround the part of the card you want
4. Right click on your crop and click Cut
5. Open a new Paint screen and Paste your selection.
6. This is where I think you get confused- Under File click Save As, name the file and remember where it's being saved to.
7. Go to your upload place, browse to that file and upload it.
8. Right click on the correct link (see above) for your uploaded file.
9. Open your post, click the Insert Media AND DELETE THE HTTP THAT IS ALREADY THERE.
10 Right click on the now empty address box and paste your link there.
11. Click insert-I promise you your pic will show up in the post.
Like that Little Red Engine chugging up the hill.....You can do it, you can do it.
Make us proud, brother cate.
