need some indication that images are still loading

[sharadagarwal]

When loading a topic feed, there is a spinner that spins while fetching the feed from the server. After the feed has been downloaded, the spinner stops. But some images may still be loading. During that time, the user experience is strange - the default image icon is visible for topics, but it is not clear to the user that the topic image is still loading.

I propose one of two solutions:

1. spinner continues to spin while the images are loading
2. use a different default image icon for topics/comments/users that have an image but the image has not yet been fetched; this default image icon could have some text that says "loading..." or some other visual indication that the image is loading. Once the image has been fetched, this default icon will be replaced with the actual image.
