I'd like to have an image host that is faster and doesn't have any limit on the image upload quota. Also, the allowable bandwidth should be unmetered, no restrictions it on it either.

A user system from where I can manage all my images, rename them, generate thumbnail, resize them.

For example, you can have it like an automated system.

http://imgdomain.com/image/myimage.png <-- Original Image
http://imgdomain.com/image/myimage_1024_768.png <-- Image Resized to 1024X768 pixels
http://imgdomain.com/image/myimage_123_123.png <-- Image Resized to 123X123 pixels

So what I'm trying to say is that, whenever I put imgdomain.com/image/myimage_WIDTH_HEIGHT.png, it should display the output as of the defined resolution. I don't know if this is even possible, but hey ! it can be a challenge

A simple firefox plugin from where I can rightclick and take screenshots. Something on the base of this plugin PIXLR
