Hi,
Inclusion of gif images from the web does not work. For example:
\starttext
\externalfigure[http://upload.wikimedia.org/wikipedia/commons/a/a0/Sunflower_as_gif_websafe.gif]
\stoptext
It is a rather strange bug. In grph-inc.lua we have
local newbase = file.addsuffix(newbase,newformat)
local newname = file.join(newpath,newbase)
Now, since the webaddress has a dot, newbase has a dot. file.addsuffix does not
change the suffix if a file already has a suffix (and does not give any warning
about it!). So, newname does not end with .pdf, and therefore
gm convert long-path.gif long-path
does not convert to pdf--the resultant file is a gif file. Hence, direct
inclusion of that file fails.
A simple fix is to change the addsuffix line to:
newbase = newbase .. "." .. newformat
