I need 1 line of text added 'HOOF PUTTY' to a photo (pack shot style) of one of our products. There is white space allready where the new text should go. Font to be calibri and same size as existing product name text. To look as realistic as possible as if it was on label when photo was taken. Have image as a high and low res jpeg. will need output to be low res (for amazon listing)
