This is a short 'How To'. It seemed necessary because of the issues with linking to photos from flickr, 500px, and elsewhere that some users were having. This is just a simpler way (or so I think).
STEP 1: Go to imgur.com
A lovely little photo sharing site that many of us know and love. You can just drag and drop a photo onto the front page and click upload, but it is easier if you create a profile so that you have better photo management.
STEP 2: Choose which photo to upload, either by browsing for it or dragging and dropping
imgur is really very simple and straight forward to use. I tend to just drag and drop.
STEP 3: Click 'Start Upload'
It's that simple.
STEP 4: Click on the image
Now this is the important step. Once you've uploaded the image, you must click on the image. It will open a page with just your image and a URL that begins with 'i.imgur.com/'.
That i.imgur.com link you will then copy and paste into whatever thread you need to, like so:
In the comment box, click the 'Image' icon:
A little pop up box will appear, asking you to enter a URL. This is where you paste your i.imgur.com link:
STEP 5: Preview your comment
You always want to check and make sure it worked.
And there you have it! Hope this helps!
