1. Go to the backend of your website: <yoursite url>/administrator
2. Once you have logged in, go to the "Article Manager".

Multithumb is accessible through articles. So any gallery or images will need to be in an article. For this example it is assumed that you are applying multithumb to an image that is in an existing article.

1. Find the article by searching through the list or using the section and categories. More on editing articles here.
2. Click on the name of that article to bring up the editor.
3. Select the image that is going to have the multithumb effects applied to it. Then push left and then right on your keyboard. This positions the curser where it needs to be to apply the effect.
4. Next, type in:
   {multithumb popup_type=slimbox resize=600}
   A quick explanation of the arguments:
   1. Popup_type – this is what type of popup style to use. Multithumb has four different types:
      1. Slimbox
      2. Greybox
      3. Lightbox
      4. Thickbox
   2. Resize – this forces the image to be displayed at a certain resolution. 600 – 800 is generally a good range. It allows for most computers to see the image without it being too big.
      1. You can experiment with large and small numbers and see the different results.
5. Then press right and type:
   {nomultithumb}
6. These are the tags that tell multithumb that it needs to do something on this page. The tag {multithumb} tells it to start and {nomultithumb} tells it to stop doing things.
7. Click on “Save” and go to the front end and check that the effect works.

It is assumed that you are creating a gallery on a brand new page. However you can still do the exact some steps and create a gallery on an already existing page.

1. Create a new article. If you do not know how to do this, go here
2. Once you have entered in the title, and section / category. Insert and upload an image. It is important to d this correctly.
   1. In the image manager, create a new folder and name it whatever you’re going to call the gallery.
   2. Upload all the images that are going to be in the gallery into the folder that you just created.
   3. Insert one of the images into the newly created article
3. Once you have done this. Click on the image and click on the “Insert/Edit Image” button. In the “Alternate Text” field enter:
   mt_gallery:<gallery name>
   Where <gallery name> is the name of the gallery that you are creating. For example a gallery of holiday snaps in the Carribean. You would enter mt_gallery:Carribean Holiday
4. Now, click on the image and push left and then right. This is to line up the curser to the left of the image, and then type {multithumb popup_type=slimbox resize=600}.
5. Push right again and type {nomultithumb}
6. Click on “Save” and then go and check how well the gallery turned out on the front end.

For the most part, using the automatic gallery generation is the best way to go. However it is still possible to create a gallery manually.
This method is very useful when the images that you are using for the gallery are already on your website and you are just wishing to add them to a centralised gallery.

1. Create a new article or find the article that you wish to add the gallery to.
2. Click where you wish to add the first image and then click on “Insert/Edit Image”.
3. Using the Image Manager, find the first image that you wish to insert. Click on it, however do not insert it yet.
4. In the “Alternate Text” area type the name of the gallery that you wish to create. For example “The Bees Knees”.
5. Insert the image and then find your next image and select it. Repeat step 4 and enter in the exact same Alternate Text.
6. Repeat steps 4 and 5 until you have all the images that you wish to be in the gallery.
7. Then, click on the first image and push left and then right. Then type:
   {multithumb popup_type=slimbox resize=600}
8. Click on the last image in the sequence and type:
   {nomultithumb}
9. Then click on “Save” and go to the front end and check if your gallery works.

You may have noticed that there are some arguments on the end of a lot of these {multithumb} tags. These arguments override the main settings. Thus allowing you to create custom setups per page. Here is a website that allows you to create the tags using some simple options: Multithumb Tag Generator
