I have a picture of the font types. I tried to submit the picture (JPG file) but I am required to submit a ttf file. I don't have it, and I cannot produce it.

what can't you produce it ?
You should use one of the softwares mentioned here : http://www.dafont.com/soft.php#3

you should read this to learn how to make a font : http://www.smashingmagazine.com/2010/11/16/web-typography-100-educational-resources-tools-and-techniques/

A JPG picture is not a font. I can be an image of a font but it's not a font.
A font is a vectorial file with a TTF or OTF extension.

On DaFont, only the true Font Files can be uploaded.
You still have to work a lot to generate a true font file.
