I take a screenshot of my desktop on my computer, but when I transfer the photo to my iPhone, the resolution drops. Is there any way to transfer the photo so the quality isn't reduced? I can't read what I want to be able to read heh.
iTunes has done this since the beginning, to save space on the phone I guess. Never heard of an option to disable that, but try emailing it to yourself it should keep its quality
It's to save space. There's no way around it with the built-in method.
If you need full size photos, get one of the "virtual flash drive" kind of apps.
Something like "Dropbox" (works over the internet) is good if you have fast 'net access all the time.
Otherwise get something like 'Files' which connects over local wifi and then stores the photos on the phone or iPod even if you're off the internet later.
