hide pictures on xperia z1 w/out complication of .nomedia & no use of apps

Hi guys,
I have been searching around trying to find a way to temporarily hide my pictures from the general album view on the Sony Xperia z1 (just got it new). I dont want to use an app as apps can cause problems...so I heard that another solution is by making a .nomedia file. However, after reading the thread on the folowing link (http://androidforums.com/sony-ericsson-xperia-mini-pro/568317-hidden-files-pc-question.html#post4584979) i saw that there are some complications; namely that putting a .nomedia file into a folder with pictures will make them totally hidden when accessed through the PC except ones that are newly added.

I used to have a bb and one could easily select the files, go to properties and make it hidden. to then see them again you would go to explorer and click show hidden. This was simple.

So my question is how can I select files, hide them in a folder and at an time on my device see the hidden files without any complications as those experienced by user Dkier on the thread linked above in brackets?

Many thanks and Best regards,

D
