[jQuery] sign preview

[jQuery] sign preview


I have a client that needs a web tool that will allow users to upload
an image and preview that exact image on a sign template. Also, to be
able to type text into a field and preview how that text will display
on a sign.
Similar to zazzle's custom product creation and buildasign.

Does anyone have suggestions on where I should start?
