As has been brought up a few times now and as space on server is not so much of a concern anymore thanks to mc101
I have enabled the attachments option on the site
It will only allow common web images types such as .gif, .jpg and .png and a few other misc file types such as .pdf, .txt,.zip (there could be others but cant remember)
To use simply click the "attachments and other options" option below the text entry box
then click the "choose file" button and browse to the file you wish to attach
there are a few limits on sizes and number of images per posts
but overall should make the process a little bit easier for all
