1. Click on choose file, and select the image from your desktop.
2. Your image will go into the box and will be overlayed with an orange heart.
3. Right click on the image in the box and click save image as...
4. The image saved will be a bit more colored than the image in the box so make sure you check it.
Now copies the resolution of your image resolution!
Reason for not all pictures working:
1. File resolutions too large.
2. File size too large.
3. There's probably a few more lets be real.
I am looking into fixing these or finding a work around for them.
Let me know if there are any other features I should add or if you have any issues.
