About Uploading Files on Dashboard
After you log in to WordPress and click on the Dashboard menu at the top of the screen, you can upload files with the Flash uploader.
WordPress supports uploading the following file types:
Not all webhosts permit these files to be uploaded. Also, they may not permit large file uploads. If you are having issues, please check with your host first.
Note: If you are having problems uploading files with the default Flash uploader, you may want to use the Browser uploader instead.
Note: If the file does not open, then the file type is not supported, the chosen format may not match the file’s true format or the file may be damaged.
