Aye, tis pretty easy to do even for those less computer savvy....
I use imageshack myself although photobucket does the same thing. If you just want to upload a couple of pics with imageshack:
1) Obviously make sure you have the piccies on your PC in an easy to find folder somewhere and that they are a forum friendly size - no point having a mahoosive image 3 times the size of your screen sort of thing.
Goto
http://imageshack.us/
On the front page, click on the 'browse' button . The default setting on that page is to upload a photo ( the little clicky box next to image, url, video, multiloader, file exchange)
A window will open, browse on your computer to the folder where your piccy is , find the piccy you want to upload, highlight it by clicking on it , then click open in the bottom right hand corner.
This will take you back to the imageshack page and next to the browse button is a text box - the route to the image on your computer should now be in that text box:
Then click the upload button and after a few seconds , you'll get a list of links to the image to choose from.
The one I use, which displays the image directly into your post rather than it being a link to click on , is the 'direct link to image' one. It is usually below some text that says:
"DO NOT Use Link Below when posting. Use FORUM Links above for posts"
Highlight that link and copy the link ( right click on the highlighted text and click copy in the popup window , or press Ctrl then C )
Back to RSVzone , in your post, click on the insert image button at the top ( the wee mountains type picture ) then right click in the popup box and click paste or press Ctrl then V and you're done. Press ok and finish up your post then post it.
Should do the trick.
