ive noticed adding image descriptions is unnecessarily difficult, which could discourage people from actually adding descriptions

1. you can only add descriptions to the tiny cropped thumbnail image, so generally i have to open the image up in a separate tab and put them side-by-side while writing the image description. if you could click the image for a full-res preview while typing the description, that would be magnificent

2. if i leave the text field of the image description, e.g. to look at the full size image in another window (see problem #1), when i return it's gone back to the start of the text so i have to click and scroll to the end of the image description, which is a pain if it's a particularly long description
