You really need to
resize the picture, it's too wide for the screen, and me with a 19" monitor. Leonard recommends 650 pixel width. That works, but sometimes there seems to be an advantage to reduce it more, like 400 or 500 pixel width, which allows less compression, for a picture of an engine, tank, bellcrank, etc.
I don't know your software, but if you have MS Photo Editor (comes with MS Office), I can help. Create a folder on your desktop, lable it "Test Photos" or similar. Save a picture to that folder, then work on it, creating new versions, while keeping the original untouched. Use the same title, but add a % in front for version 1, %% for v.2, etc. Keep trying, try all the buttons. Look for "more" buttons.
Then, you can go back and start over, if you gotta. Push the toolbar buttons and look for words like "resize". They don't make it easy, 'cause that would cut out the market for "XXXX For Dummies" books. Steve
Edit: Ooops, too many X's....may not make it by the X Police.
