Jac…..I don’t feel you’ve highjacked my thread. Your posting pics issue is totally relevant to the topic.
If you've gone down the imgbb route, here’s how I did it:
Logged into imgbb.
Click on “Upload”
Click on “browse from your computer”
Select file from your folder and click “open”
Click on the image preview and change the resize box to 640 x 480 and add any other info if you wish, then click “submit”.
Click upload (takes 30 seconds or so to upload).
Next, hover over the uploaded image thumbnail and click “Embed codes”. In the box that pops up, from the dropdown menu, select “BBCode full”
Then copy and paste the code into your forum post. I didn’t use the “insert image” icon, I simply pasted it into my post.
Click on the forum preview button, and your image should be there. It worked for me anyway.
Good luck!
