The recommended image converter is "convert" from the ImageMagick package.

sh-httpd is a shell script-based Web server that supports GET and HEAD methods, and a CGI 1.1 interface. It's not real fast, and it's probably not real secure, but it is really small. The Web server and it's configuration files are around 9,000 bytes total, and that's with comments and pretty whitespace. If you can run ash or bash, an inetd, and about 7 standard external commands on your system, you can have a Web server with CGI support. There's also a timeout counter that kills never-ending CGI programs, cleans up, and exits.
