There are several links with similar issues to this such as the following:
Issue in Admin Panel after SUPEE Patch 8788 installation
Image Upload issue after PATCH 8788 install on 1.9.2.4
Security Patch SUPEE-8788 – Possible Problems?
And the list goes on. None of the solutions or suggestions in any of these posts have worked for me.
My issue is that, after the patch, it dropped the flash uploader and replaced it with a new one, and the new one doesn't seem to work. I am able to browse for a file, choose the file, and click upload. The uploader shows it's uploading and then says complete as if everything worked normally, however, nothing is actually happening.
When inspecting the form for uploading in the browser console after the page has loaded:
<form action="{{url}}" enctype="multipart/form-data" encoding="multipart/form-data" method="post" target="uploadBlockIframe-{{id}}">
<input type="file" name="image">
<input type="hidden" name="Filename">
<input type="hidden" name="form_key" value="{{formKey}}">
<input type="hidden" name="Upload" value="Submit Query">
</form>
You can see that the 'action' attribute for the form and the 'value' attribute for the form_key input have not been set in app/design/default/default/template/dull/uploader/uploader.phtml
I should also mention that we are using CJM Color Selector Plus extension in which I had to change a couple lines very similar to the CreareSEO plugin here :
https://github.com/adampmoss/CreareSEO/pull/78
And also, the dull js files are being loaded properly.
Can anyone help me?!

Correct me if I'm wrong, but IMHO the Dull Uploader has become redundant after SUPEE-8788, since the purpose of the extension is to replace Flash.
Solution: uninstall Dull Uploader.
