Create an account with Photobucket.com or another photo website. On Photobucket, go to "My Albums." In the top right corner, under "Upload Images and Photos" is a tiny box that says,"Reduce to." Make sure you choose "640 x 480 (Large)." This makes sure the photos are not too big or small.
You can then upload photos to the sight by clicking on "Choose Files." You can upload one at a time or multiples by highlighting your files with the "Ctrl" button on your keyboard.
When all your files are uploaded, put your cursor on the picture you want to display on tndeer. Hold your cursor over the photo, and four "links" will drop down under the photo. Left click on the last link to the right of "IMG Code." This will highlight the link. Then right click on the highlighted section to copy it. Now go to the thread on tndeer.com. Under the last post, right click your mouse and then click "Paste." You can then type in your comments above or below the link to your photo.
