After customizing a sandbox and adding a login page banner and then publishing the sandbox, the new banner is not visible. All other customizations for the login page are visible. 

Although one is able to see the banner when go to the login page in Customization mode. Here you want to use an image that is accessible outside of an OIM session.

Solution 

Replace http://<OIM HOST>:<OIM PORT>/identity/images/oim_graphic_v1.2.png with the image you want to use. 

To resolve the issue, try the following: 

cp $OIM_HOME/server/apps/oracle.iam.ui.view.war /op
mv $OIM_HOME/server/apps/oracle.iam.ui.view.war  /op/oracle.iam.ui.view.war.bak 
mkdir /op/view; cd /op/view 
jar xvf ../oracle.iam.ui.view.war 
rm /op/oracle.iam.ui.view.war 
cp /<Location of your image>/<image file>.png images/oim_graphic_v1.2.png 
jar -cvfM /op/oracle.iam.ui.view.war . 
cp /op/oracle.iam.ui.view.war $OIM_HOME/server/apps/oracle.iam.ui.view.war 
Shutdown OIM managed server 
Start OIM Managed server 
The old image will now be replaced with your new image. 

If you want to do additional customizations: 
Create a new sandbox 
Click "Customize" on top. 
Open a new tab and go to /identity/faces/signin. The login page should be in customization mode. 
Click View > Source 
Select and edit the image. 
You can change properties of the image here. 
You can also explicitely specify http://<OIM HOST>:<OIM PORT>/identity/images/oim_graphic_v1.2.png as the background image. 
Click Ok 
Click Close 
In the other tab, publish the sandbox.
