Dave - Fred is correct. Some of the features, including the buttons to paste in photos, are available only to 1st Class members. Part of the reason is, as Fred said, to provide additional benefits to those who voluntarily support the site. Additionally, the buttons now tie in directly to a member's 1st Class web space, and when clicked, display thumbnails of all the images in that space, allowing the user/member to simply click on the photo they wish to post.
Non-1st Class members can still post photos using the
[ img][ /img] tags as follows...
1 - On any photo posted to the forums, there is a 640 pixel width limit, so you need to resize your photos so they are no wider than 640 pixels. Anything posted which is wider than that will be converted to a simple link by the first moderator who sees it.
2 - Filenames: Avoid using special characters in filenames. Stick with letters, numbers, the hyphen ( - ), and the underscore ( _ ). Also avoid spaces in filenames. Spaces, parenthesis, asterisks, punctuation marks, ampersands, etc. should be avoided in filenames as these will all cause problems when trying to post the photo.
3 - In order to post a photo, it needs to be uploaded to a web server. Photos cannot be posted that live on your local hard drive because there's no way for MLS to contact your computer via the internet and get the photo in order to display it. Most ISPs provide web space to their customers. Some (though not all) photos services will also work - sites such as PhotoBucket. 1st Class members get 100mb of web space to host their photos as part of their membership.
4 - Once your photo is uploaded to a web server, it has a
URL associated wth it. To post the photo on MLS, enclose the photo's URL in the
[ img][ /img] tags like so...
[ img]PhotoURL[ /img] (without the spaces - I had to insert them so the img tags would show up here).
I know it sounds complicated, but it's easier to do than to explain. Once you've done it a few times, it becomes second nature.

Use the Forum Bugs and Testing forum to try a few practice photos until you get the hang of it.
All - we'll be coming out with a FAQ on using the new editor soon.
