Good observations & questions that I will try to address in turn:
1) The restriction to only png is that, if this is going to be
rendered as HTML, this is the only bitmap file format that can be
displayed on all the browsers I tested.
2) If you examine the output from the following 4 -graph export-
commands you will see that the extension is not included when you use
the [,as(png)] argument:
. twoway mband weight mpg
. graph export test, as(png)
(file test written in PNG format)
. graph export test.png, replace
(file test.png written in PNG format)
. graph export c:\web\test, as(png) replace
(file c:\web\test written in PNG format)
. graph export c:\web\test.png, replace
(file c:\web\test.png written in PNG format)
thus, we have to be able to capture the different output, with and
without the .png extension
3) Ideally, one would have paths relative to the directory in which
the html log was written. Unfortunately STATA's string handling
functions don't include drive|path|filename|extension aware functions
like JUSTDRIVE( ) | JUSTEXT( ) | JUSTFNAME( ) | JUSTSTEM( ) that would
allow parsing the various file locations and their relationships
relative to each other. For ease of coding and possibility of moving
the htmllog and images to a different directory in the future, I
believe they should be in the same directory. If you hard code the
directories, moving the files will break the links. For Internet
Explorer, a reference to src="c:\web\test.png" will work, but in
Gecko-based browsers like Netscape|Firefox, it will fail.
4) I am aware on the inability to include multiple word filenames. As
a general rule, it is inadvisable to have space-separated filenames in
web addresses. I could pick up the entire filename, or parse back to
the preceding '\' or '/' but it is harder than it looks. I am unable
to find the index(...) function to which you refer although there is
an indexnot(...) function referenced under -help string_functions-
5) Any suggestions as to what verbatim options you would want,
remembering that it would be applied to all images? The <img> tag
doesn't have a lot of attributes. While good coding practice would
have the height and width explicitly specified, this only really helps
when rendering complex designs since the layout engine is able to know
the dimensions of images before they have fully downloaded. You have
the dimensions only if explicitly specified with the height(600)
width(800) arguments.
Thank you so much for your interest and I look forward to further
suggestions from you and others.

A few comments and suggestions on -grlog2html-.
1. It wouldn't take much to relax the restriction on only doing PNG
files... I think "file .* written in .* format" would do it (unless
there are any commands other than -graph export- that give this
message..., maybe there are, I can't think right now).
2. I believe Stata always includes the file extension in its message if
there is one, so the code to add .png if it is missing will not do
anything helpful.
3. Why do you remove the path, when there is one? If I put the image
into a different folder, then I would want the html to point there.
4. The code will fail for multiple word file names, e.g. if I export "my
graph.png", it will add a link to "my.png". For paths with spaces in,
you will end up with the last word before the space followed by .png. My
best 5 minute go at sorting this would be to code:
local gr_name = substr(`"`line'"', 7, index(`"`line'"',"written in ")-7)
This should only fail if the file name (or path) contains "written in "
(or is ridiculously long).
5. One final suggestion- It would be quite straight forward to add an
extra option to be put verbatim into the <img> tag.
