Photo and Video upload

Hi guys, I need help please.

We are unable to upload photos or videos on the social media web application we have built. When we click on the photo or video icon and upload a picture, the image sized gets reduced to the size of the photo or video icon and replaces the icon rather than being uploaded into the status box or comment area.

Please can you help us with this as we are unable to deploy our development without this being fixed.

The GIF feature is also not working. We will appreciate your help with this.

Thank you so much.
