It certainly COULD effect things but without seeing it, VERY tough to say.
As far as uploading... VERY EASY!
At the bottom of this box, there are options to 'Post Reply', 'Upload a File' (this is the one to click), and 'More Options'...
Click on 'Upload a File'
Choose file: no file chosen
Click where it says: 'Choose file'
It opens to give you options to chose from camera, then a few other options that you need to pick in order to get the right one from your storage.
If you pick 'Camera', you can just take a picture from there and it will load it up, promted to be able to chose it. If you do, it gives you the option to use that pic and if you want to load it as a thumbnail or full size. I chose full size when I loaded my pics to you. Pic 'full size'
After it is done loading, you can add any message you want to send with it, the, choose to 'post reply'
You're all set and we will be able to see your pic!
