To display this feature on your forum go to your board options where you can define custom bbcode.
There, define a new custom bbcode with the following options (those are for IPB but i can help for others boards):
- name: Maps 17b
- Description: Insert 17's buddies map's image on the forum
- Example: [ map17b ]Map_Id[ / map17b] *
- CustomBBCode Tag: [ map17b] *
- Use Options: No
- Switch Options Around: No
- Custom BBCode Replacement:**Code<div style="display:none"><a href="http://www.17buddies.net" title="17's Buddies CS Maps">17's Buddies CS Maps</a></div><div style="width:100%;text-align:center"><iframe src="https://www.17buddies.rocks/17b2/Tools/17b2-BBCode.php?Id={content}&Lng=en" width="302" height="227" style="border:0;padding:0;margin:0;overflow:hidden"></iframe></div>
Then, your visitors just have to type [ map17b]xxxxx[ /map17b] * to display an image like above of the map with id xxxxx (of course previously uploaded).
Don't hesitate to ask me for further help.
