a. From URL + uncheck the box Retrieve remote file and reference locally
This option allows you to use an image already on the web. In other words, it wraps [IMG][/IMG] tags to an existing image url.
Click 'OK' and you'll see immediatly the same image you found on the internet inside your post. Be aware that not all sites allow hotlinking.
b. From URL + Retrieve remote file and reference locally
This option allows you to upload to your storing forum space the image you found on the internet.
In this example, let's upload one of the forum banners. The url of the banner is http://aarinfantasy.com/forum/images/styles/RoyalFlush/style/af-black.jpg, this url goes in the blank space.
After you click 'Ok' you will see immediatly a smaller version of your image (thumbnail) inside the post you're creating.
Important: Not all 'url' are elegible to upload with this method. If you get an error or the image takes too much time to upload, it means that the site where the image comes from doesn't allow their images to be copied this way onto another host image service. If you encounter this problem you can download the image to your PC and use the following option.
The thumbnails are clickable, to see the original size of the image just click on them after you've finished creating/editing your post.
The filetypes you're allowed to upload are specified in the menu of the uploader. In this tutorial, I'm allowed to upload jpg, jpeg, png, gif but this might be different for you depending on your user group.
I suggest to use always external image host sites, as your forum storage space is limited (it depends on your user group). To know the space you're allowed to use, go to Settings > on the side menu Miscellaneous > Attachments.
The only case I suggest you to use the forum attachments is when you want to post an explicit/graphic (R-18) image. Majority of image hosts sites delete such files, even though this can be avoided by setting all your images on a Private Folder, sometimes they get deleted anyway.
HOW TO DELETE ATTACHMENTS
If you want to delete an image attached to one of your posts, you have 2 options:
1. From your Settings
Go to Seettings > on the side menu Miscellaneous > Attachments.
Check the boxes from the images you want to remove from your posts.
Go to the bottom of the page and select [Delete Selected]
When you go back to your post, the image won't show up anymore but it will remain a small link: 'Attachment xxxxx' if you click on it, it will give you an error message.
To remove said link simply click on [Edit Post] > delete the small thumbnail that will appear > Save the changes
2. From the post itself
Select [Edit Post] > [Go Advanced] > Scrool down 'til you see [Manage Attachments] > Click on that button and then you'll see the File Upload Manager.
At the bottom you'll see the current files attached to your post. Check the box and click the 'x' at the top-right corner of the thumbnail you want to delete.
Confirm the pop-up message and then click [Done]
Common Issues
• If you don't follow the above steps and only edit your post and delete the thumbnail, you'll see something like this after saving/sumbitting the message at the bottom of your post:
If you want to get rid of it, simply follow one of the procedures explained above to completely remove the attachment.
• Another common issue when using forum attachments is that the File Upload Manager doesn't delete the images not used. The menu literally says "Uploads not utilized within one hour will be deleted" however they never dissapear from the Upload Manager.
This problem is related to the attachment system and won't be fixed for the time being. If you want to get rid of past attachments that you don't need anymore, you should contact an Administrator, aarinfantasy or Dai-kun will help you with this.
