Yes, absolutely. I have a lot of plans for this one, and it's going to be released right after There isn't really an ETA on it, but it should be released this month.
Sorry about that. It should be fixed now. Let me know if you run into any more issues with it.
I'm sorry Sushubh, but there are no plans on doing this. JavaScript makes browsing through images in albums extremely quick and easy because the page does not have to be refreshed. In fact, the entire site uses JavaScript pretty heavily, and I'm surprised you're able to do much at all without it. I suggest downloading the NoScript extension and whitelisting Imgur.
I'd be happy to look into this. Could you please provide me with an S3 URL for testing?

EDIT: It's been fixed.
Great! I'm glad to see the issue resolved itself. Let me know if you run into any more.
The limitation from uploading from the homepage has to do with the URLs that are generated. After 40 images, the URL in the end is 239 characters long and if it's any longer then Apache screws up. I can't lift this limit without changing the URL scheme.

The limitation with HTML5 uploads is that the image is processed AFTER it's uploaded. So, uploading large images will be much slower. You won't really notice much of a difference if the images you're uploading are under 1MB or so.
Thanks for letting me know about this. It's been fixed!
