First off, I see you have posted several images of real people, so I'm guessing you're planning on uploading real GIFs which are probably against the rules as well...please review our new policy on the matter:
rule34.xxx/index.php?page=forum&s=view&id=6059Secondly, GIFs are uploaded the same page you would upload a JPEG or PNG. So just do the same shit you would do if you were to upload a JPEG, but upload a GIF instead.
As far as WEBMs not working...idk man...if the file says .webm it should definitely work. WEBMs are the only file type that has its own separate upload page. Instead of going to the normal upload page, click the button right next to it that says "Upload WEBM" and upload from there.
