Hi mate, if you go to
www.photobucket.com (there are other sites but this is the one I use) and follow their instructions to sign up for an account. Then you just press the upload button on their website and upload all your photos to the photobucket website. They keep all the photos on their computers and when you want to add a picture on here for people to see you just link to it. We only have a limited storage space on here which is why the pics have to be small.
Once you have them on photobucket, you just put your pointer over the photo & it automatically brings up a set of option boxes. Just click in the one that says IMG code at the bottom & it will say "copied"
Then you just go to your topic on here & click the reply button at the bottom. Then to put the picture in press "Ctrl" and "V" together. This will put a long line of code into your reply which will link to your picture. You can then add as many pics as you like to each reply.
It sounds a bit complicated, but once you have done it once it is very straightforward.
When you are adding pics or info about your build, you need to add them all as replies in your build topic (I have renamed this topic so you can use it) , not as new topics each time. I will merge all the topics you have posted so far into this thread, so they will appear in the date order you posted them.
If you need any more help just shout!
