Using Google photos worked for me, here's what I did using a Mac but PC should be similar...
1. If you have a Google account go to Google Photos
2. Open another browser window, go to Google maps, look up your address, take a screen shot of the satellite image of your property
3. Go to the folder on your computer where your screen shots are stored and drag the screen shot into a Google Photos shared album
4. From Google Photos, click on your photo, select the "Share" icon upper right, then select "Create a link" at the lower left
5. Create an embed code by going to
https://ctrlq.org/google/photos/ and pasting your photo link into the box and selecting "Generate Link"
6. Copy the link that appears in the "Direct Link" box at the bottom of the page
7. Open your BlueSpray page. Select the "Lawn View" tab
8. Select the wrench icon in the upper left corner of the lawn image window, which opens the "Lawn Settings" dialogue box
9. For "Lawn Image Preference", select "Use my own image"
10. Paste the embed link you created in the "Image URL" box
11. Hit "OK" and refresh the page
