I'm not sure about gif images but I know videos from dtube embed here really well. Also as you may know not all tags on here are for general use. Some are only for specific things. For example Dporn is only for porn they wouldn't want someone to post a photo of their truck or something. SPT is for a game called splinterlands. SCT and CTP are investment type things. You should never use the tags SPT, CTP, or SCT. They will get mad if you use them and it could make you get less upvotes. I'm just letting you know to help you out because I want you to succeed.
