This is a very low-priority issue.
I used the code below, with a TIFF file, and compilation to PDF stopped as soon as the compiler reached the TIFF image, and it returned an error with buffer size.
The TIFF file size is 89 MB, while the JPG is 9 MB.

<image source="Quipu.jpg" width="50%">

</figure>
I used Mac's native conversion tool to convert the TIFF to JPG, and the compilation ran smoothly with flawless output.

PS In the last week or so, I've noticed that the table of contents in the PDF output is still hyperlinked, but it's black instead of blue. I like it!
