Images in tiddlywiki uploaded to tiddlyspot

Hello
I have a large version 5.3 tiddlywiki with many images saved in subdirectories of the wiki folder and accessed directly by, for example, [img[images\StringQuartet\SQ1.jpg]]

Now I’m interested in sharing the tw on tiddlyspot. The text part uploads perfectly, but I don’t see any way to upload the image directories.

I’m guessing it’s not possible to upload a tw with images handled this way? Am I right?
