All my uploaded images on profile and asset packs have randomly disappeared and only this icon appears 

Asset pack: https://robert2700.itch.io/ghost-character-sprite-pack

Does everybody have the same problem or is it just me?

Nevermind, it has been fixeed

Temporary downtime with our image processing server, should be resolved now. If you uploaded an images during the downtime it is not necessary to reupload. Thanks
