Good Evening, Jules
I saw and searched juce demo and google sites to solve my problem.
There is not an error but I can't load image. Doesn't it incorrect?
img = ImageFileFormat::loadFrom(f);
g.drawImageAt(img, 100, 100, false);
You recommended me "There are lots of examples of loading and drawing images in the juce demo.. See ImageFileFormat::loadFrom and Graphics::drawImage, etc."
I refered juce_ImageFileFormat.
