Have you tried just restarting your computer? If you did and it still didn't work, you could try running a test using McAfee or something along those lines, to see if the problem is being caused by some sort of software. Photobucket might also just not like your computer. >.<
If all so fails, you might want to seek advice from a computer tech, not an adoptables site.
Let me see if I understand this second question,
You want to know where you can post your fursona's likeness?
...And you want to know what fursona's are for?
You could post your fursona here:
viewforum.php?f=10 (It's the 'Share your art' forum.)
...And here's a description on a fursona, gotten from WikiFur:
A fursona, is a furspeech portmanteau of the terms furry and persona (or in the case of the alternative term furson, person) and refers to a character or identity assumed by a person or player normally associated with the furry fandom.
Many fursonas are based on 'typical' animal species, such as cats and wolves, but are often only limited by the imaginations of their player, and can include more extraordinary types of creatures such as aliens, angels, demons, vampires, and mythological creatures (a popular offshoot of mythological creatures is to have a hexapedal, taur-based fursona). Hybrid fursonas are also popular; furries who like characteristics of more than one animal will combine them into one creature, such as a cat/fox or wolf/raccoon cross. Some give these hybrids portmanteau names, such as "drynx" for a dragon/lynx, or "hedgefox" for a hedgehog/fox.
Fursonas are an integral part of the furry fandom; many people within the fandom have a fursona, and demand for artwork of these people's fursonas (along with conbadges, fursuits, and other commissions) is a driving force within the furry art market, providing a near-limitless array of characters for artists to draw, and likewise, providing an endless source of paraphernalia for more exuberant fans to demand, as possibilities are only limited by the offerings of artists and the wallet of the fan in question.

Third question, I'd have to go experiment with, myself. I don't usually put a lot of thought/time into my signature...
I tried my best:
[left ][img]Your%20Fursona's%20Link%20Goes%20Here[/img][ /left] (You would leave the spaces in the "left" thing out, and you'd remove this.) *All links go here*
*All links go here*
*All links go here*
*Your likes go here*
*Your likes go here*
*Your likes go here*
Yeah... You might need someone else to help you with that last question.
Anywho, hope I [somewhat] helped, and have a nice day.
