How can you tell if an bkup image is patched?

[Tonytone]

If I have an image (cue, bin, etc...) of a backup and wish to burn it on a CD-R, how can I tell if it's been patched already? Often times the image filename doesn't specify it.

Second question is, are all image backups burned to CD-R? From what I've seen the file sizes are in the 700MB range.

Last question, I have CDRwin 5.0 and the optional settings are much different than what I'm, used to. Can anyone shed some light as to the major tic areas, my drives are 100% CloneCD compatible IE RAW-DAO 96, etc... I have noticed that in CDRwin 5 there's an area where you're supposed to drag-and-drop your file name, well if I have a cue and a bin only one can by dropped? Does CDRwin process a bin without a cue?

Thanks In Advance.
