Use same image in several categories

[aenrique]

I cannot find a way of placing the same image in several categories without uploading the same image to each category. Is there a way for creating an image thumbnail shortcut to place an image residing in a category in other categories?

Same question for categories. I would like to add a particular subcategory folder (i.e. a clipart folder shortcut) inside different categories because the images are common to several categories. Is there a way to do that without creating a subcategory and reloading all images again?
