Evis plugin: can't get urls to work as image locations

Original Redmine Issue: 19450
Affected QGIS version: 3.2
Redmine category:c++_plugins/evis

macos 10.13.5, qgis 3.2,

Everything works fine when I have a file path as a location for the image but when I put a url the image does not get loaded and I get no error messages.

I erported this on stackgis a week ago and got no responses:

I'm really not sure eVis ever supported URLs. Do they work on QGIS LTR (2.18)?

https://biodiversityinformatics.amnh.org/open_source/evis/documentation.php says:

"The location and name of the photograph can be stored using an absolute or relative path or a URL if the photograph is available on a web server. Examples of the different approaches are listed below...."

I have just checked the evisgenericeventbrowsergui.cpp source on GitHub:

if ( mEventImagePath.startsWith( QLatin1String( "http://" ), Qt::CaseInsensitive ) )
{
imageDisplayArea->displayUrlImage( mEventImagePath );
}
else
{
imageDisplayArea->displayImage( mEventImagePath );
}

If it was python I would do the diagnostics myself but I am not really set up to do stuff with C++ :(

Can plugins like this be build independent of qgis as the name suggests. If so I might have a try.
I no longer have a 2.18 instance so I don't know.

if you can prove it worked on 2.18 then this will get a higher priority. Can't you install 2.18 and try?

done and no it behaves the same in 2.18 :( Clearly no one is using this feature which surprises me.

I repeat my question about building the plugin on its own (see previous comment). I am an experienced developer and I am happy to have a look at debugging it but only if I can do it without building the whole of QGIS! I am working on a Mac with XCode.

compiling the whole thing is not hard nor takes long, at least on linux.

The evis plugin has been removed for qgis 3.14 and is no longer supported
