PHP Encode Image

Programa que me permite crear una clase PHP con imagenes gif codificadas y contenidas en la misma clase. SE podría usar clase cuando tenemos imagenes GIF de poco peso y queremos olvidarnos de ubicarlos en una carpeta y subirlos a nuestro host.

Versión que utiliza un filtro de archivos llamando a un comando externo bash de Linux.

Mismo código usando un filtro de archivos usando funciones de mismo PHP. Gracias a Victor Anaya por su colaboración.
