I think that this option is still useful. Maybe not for disabling itwhen it is enabled, but for enabling it when it is not enabledautomatically. It is usually better to use the custom quantizationtables if they are better than your default quality settings. Butif they are not better, then it is nice to give a choice to the user. If the quantization tables found in the original file are not betterthan your default quality settings, then the option "Use customquality settings" will be available but not enabled. This ensuresthat you always get at least the minimum quality specified in yourdefaults. If you did not make major changes to the image and you wantto save it using the same quality as the original, then you can do itby enabling this option. -Raphaël_______________________________________________Gimp-developer mailing listGimp-developer@xxxxxxxxxxxxxxxxxxxxxxxxxxx://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
