Amazing avies Louis, but if you build them onto an obscurely coloured background like bright pink rather than white you can make ones like this transparent using iaza.com
->
(bits of the image that were white also become transparent though, and that's why you need to use a colour like bright pink or blue etc)
Yes, you're right I'll try to do that to as much of them as I can :b The white ones at least.. and will add them to the post aswell Thank you.
Post edited with transparent ones. Just some of them.. with the rest it's more complicated because of the colors &/or shadows. Corrected more 1 or 2 too

We're all the same, except we're still individuals.
