It's an easy process that will let you take full control of the images displayed in your Google+ Local page. Let's start:

1) Go to your Google+ Local page.



2) If you are already login go to step #4, if you are not, then 'Sign in' using your Gmail credentials.



3) username: your full gmail address, and your password.



4) Click on 'Photos'



5) Click on 'Upload public photos'



6) You have 3 options now:

a) Upload the images selecting them from your computer, or just dragging them inside the box.



b) You can select your pictures from an album in your picasa album online ( picasaweb.google.com )



c) Or you can upload the pictures directly from your phone (via app)



7) Once you finish, just click on 'Publish'. In just few minutes, the new images will be part of your Google+ Local page.



8) To remove the image, just click on it, then click on the trash can on top of the page. Also, you can rotate the image clockwise or counterclockwise, you can use the autofix feature, or just the 'Edit photo' option.



9) If you click on 'Edit photo', a new panel will be displayed with more options to optimize the image. Once you finish, just click on 'Save', and the new changes will be applied to the image.
