What you are seeing

The Upload button is greyed out, or the library says 'You don't have permission to upload images to this space' / 'to the global library'

#Why it happens

Uploading needs two separate Confluence permissions in that space: create-attachment AND create-page-or-blogpost. Having attachment rights alone is not enough. Folder create, rename and delete are gated on exactly the same check.

#What to do

Ask a space admin to grant both permissions. For global images, the permissions live on the CAPABLEASSETSTORE space.

What happens

Upload. Drag and drop accepted extensions.

Bmp, gif, ico, jfif, jpeg, jpg, png, svg

Anything else raises 'Invalid file type. Only image files are allowed'.

Upload. Upload button file dialog filter.

.png .jpg .jpeg .gif .bmp .tiff .webp .p

This list omits svg, ico and jfif, which drag-and-drop does accept.

Rovo / chat accepted extensions

.png .jpg .jpeg .gif .webp .svg .bmp .av

PDF, AI and PSD are deliberately excluded even though the library uploader stores them. The check sniffs the file's bytes rather than trusting the filename.

#A few things that catch people out

  • Nothing in the browser enforces a maximum upload size. An over-large file can be stored successfully yet later fail to load in the editor or through the chat tools, which cap at 3 MB and 5 MB respectively.

Found it? Good.
