Thank you for the comments on the site it is really appreciated.
I have tried this code but the image still seems to be to long for a sumsang S7. Here is the image link:
Before change:
<img src="https://www.outdoorking.com/forum/images/forumimages/default/header_help.jpg"
After change:
<img src="https://www.outdoorking.com/forum/images/forumimages/default/header_help.jpg" style="height:auto;max-width:100%;">
Do I need to reduce the size of the image from what it is at present 630 x 118?
I might have done it wrong just want to confirm.
