If you actually go the renderflyerpreview action does it show the
picture? Are you sure that your refreshflyer() function is actually
running when you reload an image?
Also, on a side not, are you using jQuery? If so, there is a more
elegant way to do some of this coding... For example, instead of using
onClick in:
"<button onClick="functionCaller(this.form)" type="button">Hochladen</
button>"
You could add an id to the button and use a jQuery selector to attach
an event handler- that way all your javascript is in one place.
e.g.(if the id was uploadSubmitButton)
$(document).ready(function(){
$('#uploadSubmitButton').click(function(){
//functionCaller code
});
});
