First, click on open image. A box will come up to select your image. I will be using a Abraham Lincoln Dollar.
Then you will want to click on the Crop and Rotate icon as shown.
Now drag the corners and sides in to show just the coin. Use the Rotate and Flip icons if your image is not oriented properly. Then click Apply, as shown below.
Now click the Save button, as shown below.
It will usually default to jpg which is fine. Medium is all that is needed. High is overkill and not needed. Images must be under 300KB, see what it says under the image after clicking on medium. If it's over 300KB just adjust the height or width of the image down. You can change the width and height here by using the boxes provided. Generally 800 on the longest side is plenty.
You'll see below my image dropped from 546KB to 123 KB after selecting medium and making the longest side 800px.
Once you hit Save As your new edited image will open in a new window for you to download or download to your desktop automatically depending on your settings..
This is the new edited image, 800px across and 123KB...
@bobby131313 this is awesome. Just used it to upload a dollar bill pic to the currency forum. Thank you so much. The step by step was so simple even I could figure it out. This will help me in posting better pic's to the community. Thanks again.
