[PyQt] images in PyQt QTextEdit widgets

[Greg Smith]

I've been trying to find examples or reference on how to take a QImage
object and embed the results into the rich text source of my QTextEdit
or 
QTextBrowser object.

The only example I found in the Rapid Gui book regarding embedded images
in the html rich text was an example of a image located in a resource
file:
"<img=':/logo.png'>"
However I don't want to use a resource file because the thumbnail image
changes based on user's selection and new images are constantly being
added to a pool of thousands of thumbnails we already have.

I did figure out how to get it to work, and that was to use a .png file
as opposed to a .jpg, which mystifies me to no extent. I thought that
PyQt could read jpg just as easily as png files, but I guess not. 

For now I guess this will be my solution. I was hoping I didn't have to
do a conversion of thumbnails that already exist, but if I have to do
so, than so be it.

How about starting with trying to access your image with QFile or
QImage.
Once, you get that part working, the rest will be easy.
