I can no longer download my images from my Smugmug site. When I try to download them through my PC or laptop, it just gives me a tiny GIF. But, I can download them through my cell phone?
On the desktop, did you use the download button in the lightbox or near the thumbnail in the gallery display? Just right-clicking on thumbnail will only get you a copy of the small image you clicked on ... when using the desktop. Confusingly, on a mobile device, if you do long press on the same gallery thumbnail, you do get a real download. If you want to download a whole bunch of pictures, you can use the Organizer. Select the pictures and hit the download button (next to the delete button) on the third line up top.
