With the recent photobucket debockle, I figured that I would write an updated how to on this. We've also updated things on EM to make things much easier for you to post your pictures on the forum, and host them here too. This will ensure that the picture links NEVER break. So, lets get on with it!
Note: These are directions for Chrome. They'll be slightly different in other browsers.
1) Scroll down below where you are writing your post to find the "Manage Attachments" button.
2) This will bring up another window that looks like this. You will have the choice to browse your computer for an image, or paste a URL to another picture you've found on the internet. Both of these options will upload that picture to EcoModder's server, and resize it to 800x600 pixels (if necessary) automatically. With it hosted here, the link will never break. Once you have browsed for your file or pasted your link, click the "Upload" button. If you wish to upload more than one picture, simply browse again or paste another link and hit upload again.
3) Now that the images are uploaded to EM, you can insert them in your post. To do this, right click on the link of the image you uploaded. You can do this in the window that popped up, or below near the "Manage Attachments" button.
4) Click the insert image button above the text box area for your post.
5) Paste your URL into the box that comes up. Congrats, your image is inserted into your post!
