Well, you don't specified if you are using TRichEdit or what to format the text. I'll
suppose you are using TRichEdit, and maybe you are using SaveToFile to save the file to
disk. I such a case if you are not having the text formatted when retrieving the text again
then that could be because you have the PlainText property setted to true in the TRichEdit
object. Try setting the PlainText property to false, and use the methods SaveToFile and LoadFromFile of the Lines property to save and retrieve your text. That works saving the text in RTF format.

Did you tried the SaveToFile method of the Picture property of the TImage component?
