This question already has an answer here:
Ok, so here's the deal. I have a picture, from Google Images, that I am trying to put on a flashdrive or such so I can make it the profile picture to the account I am currently logged into. I have the latest OSX and everything is up to date. I am on a Safari only guest account. Whenever I try to download anthing to the computer directly, I only get a "Safari could not download the file “Just Another Day For Arceus.mp4” because there is not enough free disk space. Try deleting documents or downloading to another disk." This of course, was trying to download a video, not the said picture. That, and when I try to right click items, the usual white bar with several items does not appear. I can access the USB, however, when I go to Google's homepage and click "Change Image" and although I can access the files already on it, I cannot add any new files. Please help if you can, and let me know if I can do anything without logging into the Admin account. Also, I am not much of a tech person, so if you try to give me pathways, I won't know what to do with them, nor how to use them.
Thank you so much in advance,
