Imageshack is clunky and slow and I'd rather rely on myself to host images. I have a webhost, and I'd like to install a PHP application that'll give me a browse prompt, or let me give it a URL to get the image from, and then host it on my webserver. After that, it should give me a direct link to the image as well as some thumbnail code so I don't have to post the full image.
Can anyone recommend something written in PHP or similar that I can install on my server? As absurdly simple as the requirements are, I'm having trouble finding anything that suits them. I want something simple, not a goddamn image gallery function that I'll never use.
