I have a little problem right now, I would have to upload a picture from my laptop to my iPhone, I want to do that with ICloud, I already logged in, but I can't load the desired picture onto my iPhone, it only says a Jpeg File… Okay, so I took a look at how to change that, but unfortunately I can't change the picture to another file, why is that and what can I do?

Just open your own in a picture program (Paint or similar) and "Save as" file type Jpg, or export as Jpg. Depending on what program you have. (Assume Win. I don't know my way around Mac, but would have to be similar if you have a Mac…)
