I can't get into any of the URL links you provided. Maybe because you have security turned on, but also for RootsWeb I must be a member and at this time I am not a member.
I note that your instructions include talk about HTML. Strictly speaking HTML should not be part of a GEDCOM, but the issue here is where does the HTML point and do you need to provide some password to get at the site noted in the GEDCOM?
Anyway....
I may have missed in the instructions where/when you save the GEDCOM output from ACOM. If I missed this SORRY for not reading well. But, if you are loading to your computer from ACOM a GEDCOM file I would love to see a snippet of the file to see what they produce for the NOTEs and OBJE (picture) values.
NOTEs can come in two forms, a note about a person would look like this in the GEDCOM:
1)
0 @I2@ INDI
1 NAME Mary Ann /Wilson/
1 SEX F
1 BIRT
2 DATE BEF 1828
2 PLAC Connecticut
1 FAMS @F4@
1 NOTE @N3@ <= Here is the Note as a pointer to a NOTE record
0 @N3@ NOTE
1 CONT text of note
1 CONT text of note
2)
0 @I2@ INDI
1 NAME Mary Ann /Wilson/
1 SEX F
1 BIRT
2 DATE BEF 1828
2 PLAC Connecticut
1 FAMS @F4@
1 NOTE
2 CONT text of note
2 CONT text of note
Either version is correct but both projects/programs need to understand the other or the NOTE will be lost.
You can look at these yourself by opening the GEDCOM output from ACOM before you load the file to RootsWeb.
I'll add more about pictures later, they are much more complicated and from GEDCOM standpoint.
