i know things r a litle crazy at the moment ,but reading thro certain websites there is uniqe images and images with so called blockers ,which have supposably avoid the lastest stings can anyone confirm this
Yes, images with blockers exist but they have their own set of problems. Blockers tend to make the cards inflexible and prone to missing mandatory updates.
Custom images also exist but obviously they are custom. To make these images you need to learn how to do it yourself. If one of these images becomes public then it becomes as vulnerable as any other public image !
