You can not "upload" images directly to CanvasCampers, you must store your images on an image service like [s]Webshots[/s], Flickr or PhotoBucket or one of many other images servers.  Most are free.

Once you have uploaded your images to an imaging service, you may link individual images to your posts.  Each of these services functions differently as to how they allow you to link to your images.  Most has a screen that says "Link to it"' or "Photo URL".  The link will always end with  .jpg or .gif.

Once you have the URL to the picture, in a new topic or a reply body, enter:

[nobbc][img]http://URL OF PICTURE [/img][/nobbc]
The trick to making this work is the [nobbc][img][/img][/nobbc] tags.

Example using a group rally banner:

[Image Can Not Be Found]
What I entered was:
[nobbc][img]http://canvascampers.com/images/rally_banners/lackawanna_sp.png[/img][/nobbc]

It's that simple.

I hope this makes sense and is helpful.  Other useful forum tips can be found at https://canvascampers.com/index.php?board=26.0
