I recently changed mine to show the CT logo on clothing - and have changed it several times before - HOWEVER trying to get back to an old picture used before I cannot get the change to happen - I must have tried almost a dozen times - is it me or is there a glitch in the system. I have also tried another picture used before?

Apologies if I am telling you things you know already, but this may help some understand what is going on.
In order to help pages load more quickly, devices such as laptops, computers, phones etc have something called cache memory. Essentially this consists of bits of information which your device collects, noteably (but not exclusively) graphics/pictures. When you load a web page, to help a page load quicker, it loads the information you have on your device (the cache). if you are all seeing different pictures, it is basically what your device has loaded into its memory to help the pages load quicker.
If you press ctrl + F5 this will force your cache to 'refresh', therefore you will essentially be asking your device to reload the website from scratch for that particular page. However, if you want the device to reload all images from scratch on all pages you visit, you would be better off by going in to the settings and doing it manually. THIS website explains how to do it. Each browser (I.E., Firefox, Safari etc) has it's own cache, so scroll down on the website link for the one you use.
Hope this helps someone - apologies if I am 'showing granny how to suck eggs' - 
Also apologies if I have simplified things a little.
