Alas, the RH 6 hyperlink dialog for auto- and custom-sizing
popups lists .htm files and bookmarks only. As you have discovered,
you can use the "Display in frame" feature, specify a new window,
and you get your popup. But you lose the click-close feature. The
user has to click the "X."
I'd like to make a couple of points.
1. Direct placement of any file into the project's Windows
directory deprives RH of the "knowledge" that the file is part of
the project. When you insert a link to the file, RH adds it to the
project list.
2. You can import images as baggage files, and RH will keep
track of them in the project database. However, popup dialogs don't
list baggage image files.
3. Instead, I save screen captures elsewhere. I often crop,
resize and otherwise fiddle with images for graphic effect. I
prefer not to work from the graphics application in the RH project
folder, because I would have to keep careful track of which images
already are linked. Resizing a linked image distorts the output
because its original dimensions are in the html code. I would have
to go back and re-link to the revised image.
4. When it's ready to be brought into the project, I import
an image into a new topic, sometimes with a headline or caption,
but usually with no text. If I have a lot of them, sometimes I add
a folder to the project explorer for popups and use a file name
like homescreen_pop.htm to remind me of which topic it belongs to.
Since it's an htm file, it appears in the popup hyperlink
file list.
Yes, it's an extra step. I find it well worth the trouble.
