Some options:
(1) In the notebook you can upload photos to a worksheet. From a worksheet
click on the Data --> "Upload or create file" option. If you select an image it
is then associated to the worksheet. The image can come either from a local
file on your computer or from the internet. You can then just refer to
the image directly, e.g.,
html('<img src="panda.jpg">')
like at

(2) Though not optimal, the following will work fine if you have, e.g.,
an image in /home/was/c.png:
os.system('ln -s /home/was/c.png .')
html('<img src="cell://c.png">')
This will make the image appear in the current directory (or whatever
html you're doing). Of course if you upload the worksheet elsewhere,
that image will break (whereas with (1) the image will still be there).
