Looking at your Icon Deposit site, about 50% of the images are loading for me. If I click on the "Files" link on your home page, there are about two pages worth of files, so I suspect all of them are there.
What is going on with my site, all my downloads are gone!!!!!!!!!!! WTF!!
On this page, the download button image does not load, but I was able to guess at its location - clicking there allows me to download the PSD file. So it seems that the data form files are still available.
I understand that this is causing problems for you, but just thought I'd let you know that I was able to access those files … and therefore, all of your work and the work of your contributors is not permanently lost.
