I'm glad to help, and you know I want to see your pictures from LA, so I have an ulterior motive. First of all, do you have your pictures on your computer? I can't help you with that part unfortunately, but I'm hoping you've already done that.
The next step is to figure out which picture or pictures you want to post. Sometimes it's fastest just to copy them onto the desktop where they're easy to find, or you can make sure you remember what folder they're in and how the ones you want are labeled.
Next, go to the site I've linked below. You'll get a page where you can choose the file you want to upload. If the "upload: file" choice isn't already selected, do that first. Then click on "choose." A window will appear in which you can select a picture file from your computer. If it's on your desktop, make sure that "desktop" is selected in the center menu on top. Otherwise, select the appropriate folder. There will be a list of files and/or folders from your computer. Click on the picture file you want to select it, then click on "host it!"
After a few moments, another page will appear with a number of URLs on it. I always use the very last one, called "direct link." Copy the URL you want and paste it into the "Optional Image" line or directly into the message itself here. Your picture will then appear within the message. Over at IMDb, it will only appear as a URL in the message, which you can make into a direct link by enclosing it within [url] and [/url].
