@Megaserlex You should make sure to read howto:Upload and howto:Tag before uploading. You should upload by either using the bookmarklet or putting in the direct link to the source whenever possible, and the source will be marked on the page.
Further, judging by your name, you seem to be uploading your own work. This is against Danbooru policy, and makes it very unlikely to be approved. (Meaning it will be deleted in three days.)
