Another PhotoBucket user here. Create a user ID and all you have to do is drag and drop you photos to the main directory which opens automatically. Once the photo is uploaded, you can click the image and it opens up. On the right side will list a set of URL's for the photo. Copy the URL and past it in the RV.net forum. You can create folders and upload to folders, or move the photo around. It does have some editing features, but I edit before uploading, so have used that feature very, very little. You can also protect your access so only you can view anything, or leave it open so others can view, if they know your URL.
Here's a link to my main bucket if you want to explore a little. I don't have anything "private" on Photobucket at all. I started using Photobucket exclusively so I could post photos on RV.net. So, every photo on there has been posted on these forums at one time or another over the years.
Click here - Main "Bucket".You can also create slide shows. Here's a link to a slide show from one of folders. Here's a "link" to a 6 photo "slide show" of my previous Satalite TV Dish Tailgater's and antenna"
Click here.So PhotoBucket is pretty easy to use, and has some nice features too.
Once you've tried it, you may like it. No harm in setting up a FREE account and putting up a photo and see how it works. If it doesn't work for you, you can simply abandon it! No damage done!
