If one were togo to the Gallery page, one could expect to see something like this, but with real pictures:
What you may NOT see is what is foundfurther below:
It is possible to upload to Gallery, but you have to SCROLL DOWN to see what's closer to the bottom. The upload function is there. If you DON'T scroll down, you won't see it and will not understand how to use this feature.
However, it may happen that when you scroll down, you get to the bottom and don't see the upload function. In this case, you have options.The oneI've discoveredis to select a different "Pictures of" or "Order by" option. The green arrows in the image below show this.
Of course, whether or not to upload to Gallery is entirely up to you. The photos you post to your OWN page are yours to do with as you like. Those posted to Gallery can only be deleted by the site owner, and you would have to contacthim for that.
