Of course:) First you must log in with steemconect then you press the purple button with the arrow which is under the yellow one. Then it takes you to the upload image page, ther you choose the aspect ratio and you upload the photos. Sometimes it is better if you upload one photo and then add the rest by editing the steemit post. After you upoload the image you go to the next page where you put the title and the text. When you are ready you must first close all tabs at your browser and then press submit. You leave it to load for a while and then it says that it is succesful.
