I'm new to posting pictures and was wondering how to post them as attachments. I tried to attach some pictures but it says the type of file the pictures are in are not allowed. I saved them from instagram and it says their jpegs but it won't let me attach them.

Hmm... the file extension for the pic in this post is *.jpeg, so that is accepted.

There must be something funny/unusual about your files.

I can think of two options for the set you're trying to share:
1. Get an account at MEGA.co.nz, or a Google Drive, or whichever hosting site suits your fancy, and upload a zip file.
2. Email everything to me (PM first) and I can take a look for you.

Thanks I figured it out though when I saved the files I renamed them so I could order them I accidentally deleted the .jpg

I can't add my avatar no matter how big or small it is.
