Dutch translation added.
Thank you! I will include in the next package.
I found a problem with Dynamic IV. When browsing through pages Dynamic IV block itself when you use history-1/backspace the encrypted string has become invalid for Mask URL. The browser just servers the cached page.
After doing a reload/pressing F5 all encrypted strings are generated again and all is fine again.
Well - the tighter the security, the more things will get caught...
I can't recreate what you are seeing - the only time I see an error (non-displayed image) is at times trying to right click and view image - which is going outside Coppermine... Even use of my browser's Back button hasn't caused additional errors.
Perhaps another plugin getting in the way?
Let me know the details of what other plugins you use and exactly how you get the error - and I will look into it.
I think with the combination of options available, an appropriate balance can be found by someone wishing to use this.
The mask/encryption options combined with the URL options give a variety of choices.
And if not - I welcome ideas for additional choices (Dynamic IV being one of them I added at other's suggestion...)
