Why do you think you need the modify the default launchers on Windows? As far as I know FreeCAD uses QTWebKit or QTWebEngine for displaying the HTML Startpage. I don't think the default system Browser is used for this purpose, but maybe i'm wrong. But then the QT4 and 5 builds shouldn't behave different regarding image display, because I have always the same default Browser for both builds.Syres wrote: ↑Sat Jan 12, 2019 11:52 am@yorik please see https://forum.freecadweb.org/viewtopic. ... 94#p279594 , it's not a clean method for getting the icons working on the Start Page. I'll see if I can find appropriate hardware to do a vanilla install of Windows 7 and I have access to a Windows 10 box of a family member to generate a repeatable fix of registry keys.
I have fixed all <img src> tags so they're all using a file URI. To make the documentation section work, there is also a new html template neccessary.
I have tested with both py2/QT4 and py3/QT5 builds on Win10. They both show now the images. There was no need to change any file association on my machine. The only issue I have is that the last used files are only displayed with my py3/QT5 build. With the py2/QT4 build these entries are missing completely. But this also happend when the unmodifierd files are used, so I doubt this has something to do with the modifications.
It would be interesting if this modification als works for Linux and MacOS User.
