Same situation here. Initially (about 3-4 days ago) I was receiving an Error #2049 message.
That went away about two days ago, but now I am unable to create viable links.
The upload process goes through to 100% - and the page says it was successful - but when the result of the posted image is displayed, it is just a tiny square without any image.
The links (all of them) that are created for an uploaded image are dead-ends.
Logging in and out made no difference, nor did switching browsers from Chrome to IE8.
Running Flash Player version 21.0. Have cleared browser's cache and reset Chrome flags to default.
Tried re-registering under a new user name/password. No change.
This appears to be a TIH specific issue - I am still able to upload images via Image Venue and directly to various forums as usual.
And another thing - I just noticed that the sample images shown in the box on the RH side (formerly of Taylor Swift)are also just dead-end little squares.
So, since the sample images are not viewable, it would appear that this isn't an uploading issue, but rather there is something wrong with the way the server is downloading images from TIH.
Let's hope this gets cleared up quickly. I really like TIH and would hate to have to switch image sharing sites.
