IT'S FINALLY DONE AND INTERGRATED WITH THE SERVER AND FULLY WORKING!
Go here to test it and make your own NG-Bot userimage NOW!

Guide:
In the left tab you just click each of the text areas to edit the text. While selected a text area, you can change the color of that area from the right tab or edit the text. When deselecting everything you're able to edit the color of all elements.
When you're done, press generate and the browser will be sent to your newly generated gif image. Save it and upload it as your userimage. You're done!

Leave all feedback in the comments of this page. If you find any bugs, tell me and I have them sorted and have the generator updated in no-time.
