Please reference this post that we made on March 25th.
Since diskspace is not a resource that is unlimited we had to make some changes to help manage our disk space on the server acount. In checking your profile it reports you have 3.3MB in uploads. This is more than 300% above the standard alotment for uploads since the change.
If you wish to upload more images you have a few options. First you could upload them to the photo gallery. You have a 1 MB quota over there and the images you have attached as posts do not count toward your photo gallery uploads.
Another option would be to visit your profile via the following link.
Click on the attachment control panel to view the images you have uploaded and delete the ones you can part with.
The last option is to make a small donation to the website. Out of thanks we up your specific quota from 1MB to 4MB. You can read more about this at the following link.
