[Qt-interest] QWebView HelloWorld - image doesn't load - solution

[Hawkeye Parker]

"The [imageformats] dlls need to be located in your application's executable directory under the sub directory imageformats, like so: 

MyApplicationDirectory/imageformats/qgif4.dll"

You can find these dlls in \Qt\4.6.0\plugins\imageformats

This solved my problem.  Many thanks to Eric and all others on this great list who helped with this issue.

Thanks again and Happy New Year,

Hawkeye Parker
