Hi Jason, is the problem solved? I have similar problems with the image upload in PDF action too. Maybe this helps.
We are using the Cloud version too. The Download PDF Datalist Action Plugin's version is 5.0.0
The image that I have uploaded using the "Image Upload" form element is shown in the PDF but no matter how I change the size of the image in the form, the PDF doesn't change. Second; if I upload the image in the "Rich Text Editor" form element, it is not shown in the PDF.
Apart from the "Image Display" size, I haven't changed anything in the image upload form element. The image I tried is a screen-shot = PNG file.
So the image is displayed in the PDF but the size of it can't be changed.
The image in the rich text editor is not displayed.
Does this help you and can you help me?
Thanks in advance,
Sebnem
