Hi textool. Welcome to the forum! I am pretty new here also, but from my limited experience, these guys are very knowledgeable and are good at answering a plethora of questions. And I'm fairly confident that Square_peg is one of the aforementioned "axe detectives" himself. He and some of the others know more about axes than I'll ever know. So, since I can rarely if ever answer any questions regarding axes and the like, due to my limited knowledge, I figured I'd try to help you out with posting a picture. What Square_peg said was correct about hosting on another website, but I'm gonna try to go more in depth because I too thought it was difficult to figure out. Here are the steps.
1. Google the word Photobucket. Go to their website. Start a free account with an email address. Don't use your Facebook account. They'll just spam your account.
2. After you set up your photobucket account, click on the upload button. Choose the pictures you want to upload. You should be able to upload multiple pictures at one time.
3. Once they are uploaded to photobucket, you then need to copy the link for the picture you want to use on the forum. To do this, click on the picture you want. On the right side you will see a section called "links to share this photo". There are 4 different types of links. You want the second one down called "Direct". Copy this link, the whole thing. It should start with http.
4. After you have the link copied for the picture you want, come back to bladeforums. To add the picture, you need to start a new thread, edit your old thread (which is what I figure you will want to do), or reply to a thread. Once you are starting, editing, or replying to a thread, look for the button just above where you are typing that looks like this-
Click on that button. When the box comes up, paste the link you copied into the box. Then click "Ok". A line of text will appear where you wanted the picture. It will have the word before and after the text. You can preview your post if you are in the advance setting (click the button "Go Advanced" to do so). Or just hit the "Post Quick Reply" or "Start Thread" button. Again, if it doesn't turn out the way you want, you can edit your post by hitting the "Edit" button.
I hope that helps. I know it seems like a lot of steps, but once you do it a few times, it's not so bad. Good luck! I'm looking forward to seeing your new discoveries.
