Hi Abdelatif,

Unfortunately, not all file types are supported for portfolio thumbnails and attachments. Please, see this help article for more information.

On websites, "index.html" has a reserved meaning.

Name your file something else and you should be able to upload it as a portfolio piece.

Clients don't care what your file names are. They just want to see examples of your work.
