Can you take a picture and get it onto your computer? (It's probably easier from there than from a phone).
If so, showing us a picture is an absolute doddle. You simply need to go here
http://upl.co/ and click the green button.
Navigate to the location of your file and double-click on it.
When you see a thumbnail of your image, click in the 'Direct link' field, to highlight it.
Then right-click and select 'Copy'.
Return to this thread and post an answer where you simply right-click and select 'Paste' to put the link here. (It's best to put it on a line by itself).
