How to link to images hosted on other services
Flickr:
1) While viewing the individual photo from your photostream, click on the
Download button (in the lower-right corner), the select
View all sizes:
2) From the list of possible sizes displayed above your image, click on
Large 1024 (1024 × 768).
3) Right-click on the resulting image and choose
Copy image location (might be slightly different wording in your browser). The link will look something like this:
https://live.staticflickr.com/65535/...782100c0_b.jpg
4) In your forum post, click the
Insert Image icon and then paste the image link:
Other hosting services:
For others who don't use Flickr, you need to upload your image to some other hosting service, then link to it from your forum post. Here's the process for doing this in
Imgur, but it will be similar for other services (like
http://postimages.org,
http://imgbb.com, etc):
1) Go to
https://imgur.com. You don't need an account.
2) Click
New Post to a create a new post.
3) Drag a saved image to the page, choose it from your computer, or just paste it from your clipboard.
4) Once the image is uploaded and displayed, right-click on it and choose "Copy image location" (might be slightly different wording in your browser). The link will look something like this:
https://i.imgur.com/abcdefg.png
5) In your forum post, click the
Insert Image icon and then paste the image link:
That's about it. Once you get the hang of it, it's pretty straightforward.
Try not to upload images wider than about 1600px, otherwise they are too big and require horizontal scrolling in the browser.
