Hello!

I am very new to the site and, also, very clueless on some things, as you can see.
I have noticed a great amount of users have picture messages as their signatures and I am really wanting to do it, too. I tried it once following this which only ended up with not only a white background, but absolutely huge in size.
Is the transparency and and the size only determined in the program you use to make your picture in? Or am I doing something wrong considering the the steps of the tutorial in my link?

I feel stupid asking this.
But thank you for your time.

EDIT: Also, the program I used for the picture my first time was MS Paint if that changes anything.

PREVIOUSLY:
There was no response from the strange fawn. Orick tilted his head, wondering a moment before shifting uncertainly. He'd learned the hard way that not all the animals in these strange woods had the ability or the capacity for speech. He recalled how foolish he'd felt after trying to strike up a conversation with a bullfrog one lonely evening by the pond.

He could tell that wasn't the case with this fawn, he could tell... that he was aware of him... He saw just an instant of the shock on his own face before reluctantly returning to the darkness of his own mind. He was able to smooth out his expression, but his heart was pounding in panic and he trembled lightly. No one had ever noticed him before. He cursed himself, he should have known, this place was so different from anywhere he'd been before, everything was different.

"I... I..." He cleared his throat and tried again, "Tis awfully cold this day, mind that thou stayest warm and comfortable lest thou fall ill..." He cringed a bit a his own pathetic attempt at light conversation, too unnerved to worry about adhering to modern dialect. He didn't have much hope that it would fool the fawn, young or otherwise.

Undercut since they take up a bit of room :I

Look what my Friends gave me for my Birthday
