In the forum, image uploads must be under 1 MB in size or you will not be able to upload them. This is by design, as we have a limited amount of storage to work with on our servers. However, you can upload images as large as you want using imgur.com:
1. Create an account: Go to imgur.com and create an account.
2. Upload your image: Upload the image you wish to post to imgur.
3. Click the "copy link" button on the image: The button will appear when you hover over the image. Do not click the link beside the image, as this link will not work.

4. Paste the link in the image menu and add ".png or .jpg": Click the image icon at the top right of the text box and paste the link in the box labelled "source." Depending on the type of image, add ".png" or ".jpg" to the end of the link. This is important, as without this step, the image will not render on the page.

5. Click save: Your image will appear in the text box, and you will be able to size it as you wish!
