I can't seem to post my pictures, any advices?

I had a question like this a little while ago actually, I'll cut/paste the answer from here: http://beastkeeper.com/thread/5969

Well if the image is from your computer you will need to have it hosted on a website such as www.photobucket.com is one that I really enjoy. You can make an account and store your images. Or www.tinypic.com is a good one if you don't want to make an account (just don't lose the link!). You will receive a link ending with the images file extension type (like .jpeg or .png).

Once you have done that it now depends on what text editor you use. Te default is the Rich Text Editor, so I imagine you are using that. It has all those little buttons that you can click on. On the very bottom row, third one in from the right is a little tree image. Click on it. There will be a pop-up (make sure it is enabled for BK). Where it says Image URL paste the url from your upload. If your image is from elsewhere on the internet you can simple right click on the image and click "copy image URL" and paste that. 

You can also resize your image within that little popup. 

Now, if your image is in Beastkeeper you can simply right click and "copy image" (don't need the URL) it and just paste that into the text box. 

If you are using the HTML editor the process is the same but you will instead use the tags <img src="PASTE IMG URL HERE">.

You can change which text editor you are using here: http://beastkeeper.com/preferences

I hope that helped, let me know if you have more questions or need better clarification!

I hope this has helped! If you still have problems, please let me know! :)
