Quick attempt at a FAQ for this:

From the portal, on the left, at the bottom of the menu, left click once on CPS Image Hosting.
A menu will appear. If you can't see the bottom of the menu, try clicking the + to close the news
box.



Click Upload an image, a new window will open.



Press the Browse button and find the image on your computer that you want to upload.



Select the image with a single left click and then click the Open button.
The browse window will clear and the file name will appear in the box.



You can repeat this, in each Browse box, to upload up to six images in one go.
When you're ready, click the Host it button to upload the image(s).

Once the images have been uploaded, you will be re-directed to a screen showing all of your images.
Underneath each image will be some information about the image and some fields that you can copy and paste:



"BB Code IMG" You can copy and paste this text into forum posts or signatures to display the image.

"BB Code with URL" This can be used to make a clickable image that links to the full sized version.

"HTML Code" You could use this in a webpage, or maybe copy it into an email to send to friends.

"Permission" This box is important! If you want people other than you to be able to see the images
in forum posts or in your gallery, you must click Set public. Once you've clicked
it the option will change to Set Private, so you can always change it back again if you make a mistake.

Also under the Permission option is Delete Image, which you can use to remove images that you've uploaded.

Maximum image file size is 1MB (one megabyte). Maximum image dimensions are 1024x768.
You can use free software such as Irfanview to resize your images before you upload them.
