imageformats plugins

[wysota]

I ran your test program on the machine that has Qt4 but I did not detect anything happening at all.

Add CONFIG+=console to the project file, rerun qmake and rebuild the project.

Is this program supposed to list the file extentions supported?

Yes.

In order to compile imageformats dll files I have to reconfigure Qt in on my computer??

Yes.

That sounds a bit complicated for my current knowledge

So use the shared versions. They are much less complicated and you still haven't verified they are the ones causing trouble. Do that first before trying more tedious options like the one below.

Are there any step by step instructions available?

configure -help then configure <your set of switches go here> and then mingw-make or whatever your make command is.
