Some changes with determining the thumbnail resolution for imgur images
- Use full resolution when the thumbnail height is >1000 rather than
>1200
- Use full resolution when the file extension is not provided (ie
imgur.com/xxxxxxx). This is so that gifs won't end up becoming a static
picture
- Limit resolution to 640x640 for non-gif album images
For album thumnails, set the link to the image rather than the gallery
Better handler for when imgur album is empty or doesn't exist
