Here's a basic "How-To" on how you can post and resize pictures.
Posting:1) Find a website that will allow you to host pictures on their site and remote link them to other sites. A good one is
photobucket.com if they are accepting new members at this time.
2) Upload your pics onto the site you chose (I'm using photobucket as an example). You do this by clicking on the browse button at the top of the page. you can create an album for these "iguana images" if you are the organized type. It should look like this:

3) After the image is loaded, you should see it near the bottom of the page. Under the image there whould be a list of tags including URL, IMG, and TAG. Copy the link in the URL box. It should look like this:

4) Then start a new post here. At the top of new topic page, there is a button labeled IMG. Click that button and paste the URL tag of your image into the bar that comes up.
Resizing:It's easy to resize if you have a new version of microsoft. Just open up your picture in microsoft picture manager and resize it to the perfect demensions (compressing to web page size works fine). Remember to resize BEFORE uploading to photobucket.
If you you don't have a resizer on your computer, you can resize with photobucket by clicking on the "edit" button just above the photo you want to resize. Then you can edit you pic by 75% of original size, 50% and 25%. Be careful not to resize too much at a time or you'll make it smaller than you wanted.
