1Why do you want to append text to an image file? What do you have in mind here?– GalikCommented Jan 26, 2016 at 14:08

Because the I see it with sublime text– John MaryCommented Jan 26, 2016 at 14:08

This does not put the text in the image data, it puts the text after the image data and likely renders the image file unusable.– GalikCommented Jan 26, 2016 at 14:10

Try adding photo.close(); on a new line after what you have written

Technically this should happen automatically when the stream is destroyed, but the close() method should be called and does write pending data to the file before closing. Probably also worth adding error checking for file open errors.– TomCommented Jan 26, 2016 at 14:16

This won't make any difference, the file closes automatically.– GalikCommented Jan 26, 2016 at 14:19
