I'm not sure the reason for this, as when I first purchased my macbook about a year ago, and indeed up until about 4 months ago, if ever I wanted to save an image from the web onto my desktop I could simply either drag the image over, or right click and save. However, now when I try and do the latter the image is saved as a "plain text document"? The thumbnail also looks like a plain text document, yet if I open it with Preview it displays the image. I'm still rather new to macs and I'm sure it's something very simple, but if somebody could offer to advice on how to fix this I'd be most appreciative. Please remember I'm not that tech savvy, so explanation in layman's terms please. Cheers in advance.
