--- Comment #14 from Mike Kaganski <[email protected]> --- (In reply to Robert Großkopf from comment #13) I'm afraid I don't quite understand you. There are form events, including "Before Submitting"; do you say I can't replace whatever value I want with some processed data, e.g. with a processed (reduced) thumbnail of what I loaded into the control? -- You are receiving this mail because: You are the assignee for the bug.
