Figrat, not sure if I can help, but when you click on the green tree just above my message (third icon from the right) you get the following window:
You click 'select' and navigate to the file on your computer, and then click 'upload' . the file needs to be of a certain size in dimensions and bytes - I think 1 mb is the biggest - so you may need to downsize your file. Hope this is not a case of teaching grandma to suck eggs and you already know all this, and have a different problem that I have not helped with!!
