Imgur is a free and simple image hosting service with image editing feature. Signup is optional. Imgur is pronounced like image-er; imager.
The maximum non-animated file size you can upload is 10MB. However, if the image is over 1MB then it will automatically be compressed or resized to 1MB, for better viewing on the net. The maximum animated file size (both GIF and PNG) is 2MB.
Images may be removed if they get no views in 6 months. More Info »
