What you do is open the app and go under my albums. It will have a place where you sign in. If you don't have an account create one. It will look like this.
One you are signed in you can now go to upload media. And it will look like this
Pick Choose Existing. This is where it go into your photos and you can pick what picture you want.
Now once you find the picture you want tap it and it will start to upload.Ex
Then go to my albums, tap the picture you just uploaded and it will have and information option at the bottom right corner. Click it and this is where you get the IMG code that is needed to upload to lawnsite.
And then tap the IMG code and it will copy it for you. Go onto lawn site where you want to put the picture, paste the IMG code and there you go. Sorry for the huge pictures I haven't yet to figure out out how to resize them. Let know if you have any other questions.
