How do I change image category after I uploaded the image?
You do not have to remove the image to change category (for example, from general images to microscopy). Just press "Edit" button on top right corner of the page and find the words [[Category:category name]] (you can use Ctrl+F on the keyboard for this) and change the category you don't need to the category you wish the image would have.

For example from [[Category:General category images from European Science Photo Competition 2015]] to [[Category:Microscopy images from European Science Photo Competition 2015]]. Press "Save page" button.
