If you're hoping to store an image for long-term purposes, don't rely on TinyPic.

I often participate in LIMS (last icon maker standing contests), and some of these contests now caution contestants not to use TinyPic. The submission period for the contests usually last a week, and at one point TinyPic was the more popular image host of choice. I would say out of the 20 people who uploaded their icon to TinyPic, at least one entry would be deleted by the time voting went up.
Instead of the icon, you see a white box that says "this image has been moved or deleted". Gee thanks, TinyPic. Looking through archive of the icons is even worse. If someone's icon was uploaded on TinyPic in the past, chances are it's gone.

They also have one of the most obnoxious captcha to date that you must fill out in order to upload an image. They've got words that are upside down, difficult to read, and ones that are just plain illegible (words running into the next or looking like a non-existent letter). There's also no bulk uploader.

In September of last year, TinyPic was bought by Photobucket who ingeniously decided to block international usage (I quote directly from the website): "Tinypic is no longer accepting uploads from international locations, and links are turned off...To upload, share, or link content, please go to Photobucket.com to register an account."
The next day Photobucket reconsidered, but prior to that, many graphics-oriented places were already telling people "TinyPic doesn't allow international usage anymore, don't use them". Probably not Photobucket/TinyPic's smartest move.

I thought if I registered with TinyPic, I might be able to bulk upload or skip the captcha, but when I tried, they took me to Photobucket. Except I'm already registered on Photobucket. However, my Photobucket login doesn't work on TinyPic. So they want me to log out of Photobucket of which I'm already logged into, register with a new account, just so I can use TinyPic? No thanks, I'll pass. If you're going to refer TinyPic registration to Photobucket, then link my Photobucket account to TinyPic, already!

Overall experience: Terrible. Am not impressed with TinyPic and do not recommend them to anyone.
