I'm trying to create a Confluence page containing multiple images, and after uploading a handful of images, only the first two are showing up on the page's "Recent Uploads" display when I hit the "Files & Images" button in the editor. This seems like a bug? Admittedly, I can get all of the images to show up using a thumbnail gallery, but I (much) prefer the control of being able to order/lay them out myself.
Not sure if this is related or not, but instead of having to click the "Files & Images" button each time I wanted to add an already uploaded image, I'd find it much more efficient to use the former "exclamation point" method for accessing attachments.
