Back from my honeymoon traveral, i was looking for a most useful and powerful image encryption software which can encrypt my pictures. i have tried several picture encryption software, however, they all have to compress or decompress the pictures. is there a picture encryption software which can see the encrypted pictures freely without uncompressing?

Why do you need to encrypt your pictures?

If you want to protect you pictures, just burn them onto a DVD.

Honeymoon pictures so they are probably private and memories also.
I would suggest making a couple of dvd copies and store them away.

I would presume the OP was referring to a method where he or she could keep the pictures on the machine but stop anybody from looking at them.
The only solution in that regard would not to put them on the machine at all.

This comes back to the age old question that used to hang around on internet forums everywhere in days of old - I want pictures online, how do I stop people stealing them? The answer is don't put them online in the first place.

This is true but also a backup or two is worth the time just in case.,
Those pictures can never be replaced if something happens.

What about some form of password protected folder?

If more than one user has access to the computer on which the pictures are stored, then presumably, they each have their own logon ID & password.

As long as the OP stores them in his own "My Documents" folder, there's no (easy) way for anyone else to view them - at least not for a novice, and as long as he logs out when he's not at the machine then his privacy is maintained.

I guess burning it to DVD and secure it would be a good option OR a removable HDD with password protection is also good. Maxtor is one of them.
