Should you only have one copy of an embedded image?

I have four different images. I have multiple pages in a doc.

So when I call:

img1 = await pdfDoc.embedPng(imgData);

If I am to embed/attach that same image to other pages, should I use this reference eg. img1 (stored somewhere) as opposed to calling the embed function above again?

I was having weird problems where the applied images weren't saving to the page.

Further when I tried to use a recursive way to attach images as opposed to a for loop, the for loop was more reliable. The drawImage method looks to be synchronous so I don't think I have to wait for it. The recursive vs. loop might not be relevant if my underlying issue is embedding the same photo more than once.

I went with a reference, only embedding the image once on the particular doc. Also I embed all images to be used in a doc immediately instead of per page/as needed (my initial approach). The latter I was having problems with missing images.
