there are a couple ways to upload photos here,
to upload from this site
click on the host an image button above the reply box.then click choose a file. then click on the photo you wish to upload, then click open.Next click the host it button, the next screen will have the img codes, click the copy button for the code you wish to use, then right click in the reply box and click paste, your img code should be pasted, you can use the preview button at the bottom to verify it is there, to get the box off the reply box when your done, just click the host an image box again and it will go away,
from photo bucket
have a photo bucket account, then click on the green upload button at the top of your page, then click on the upload photos or videos button, this will take you to your pictures, click on the photos you wish to upload and click open, they will then upload, if you are done, click save and continue to album, or you can click upload more photos, when you are done uploading, make sure you click save and continue to album, when you arrive at your album, click and highlight the img code below the picture, then right click and copy, then you can paste it in the reply box here, it works best fo me to have photobucket open in one window, and this site open in another, that way you can go back and forth easily
hope this makes it easier for new users to upload photos, any questions, don't hesitate to ask
