loading pictures from a server

It seems like this fetch is a blocking function.
Please check the return value of loadFromData().
And check the length of image data after fetch to make sure that fetcher is fetching right.

sizeof(data) will always return the size of a pointer. You need to use the return value of http_fetch:

int len = http_fetch(urlpath,&data)
     pixmap.loadFromData((const uchar *)data, len);

int len = http_fetch(urlpath,&data)
     pixmap.loadFromData((const uchar *)data, len);

On another note, using a blocking function in your GUI thread is probably not a good idea.
