I don't quite follow what you are saying. If you would take a few minutes to create a free account and reply with a little more details.
First, your title is very confusing. Picture files will not be found in an audio manager. Audio manager will only show audio files.
Next, are you saying you transfered pictures from your internal memory of your device to an SD?
Are the pictures still found in the internal memory or where ever they were originally saved to?
