Hi,
It is impossible to upload any files directly to Nicepage Hosting. You can only publish sites to our hosting. If you need to add an image, you can use the Image Element and upload your image to the editor.
However, if you need to add an HTML code with an image, you can upload it to any image hosting and set a URL to an image in your code.
Let us know if you need our further help!
