You have up to 4GB of images hosted on your website as it seems from your publicly available backup, did you expect such a big growth in such a short time?
I didn't expect such rapid growth. I expected to reach this value only in about 6 months. But, everything turned out very quickly, and what I had planned to invest in six months, I had to invest at the end of a week of the project.
I'm glad it was well accepted.
