No account needed and it's very fast. Uplaod the picture from your HD. Then copy the tag for the Forum and paste it in to the message section. Then post.
OH and BTW. http://www.gallery.americompx.net is free to use as well. Albums and sub albums can be created along with comments etc no restrictions on how many images can be hosted. I only ask that **** noit be hosted on it and that resolutiuons stay below 800 and file size under 300k. All are welcome to use it.
browse for the picture you want to post [ make sure its under 250kb ] and upload it [ if its bigger than 250kb, it will resize it for you ]. when it loads, look in the bottom right corner of the screen, and copy the THIRD block of text it gives you where it says IMG, all you have to do is paste that in your post and the picture will show up. if you want to send the picture in an email - just use the first block where it says LINK
the thumbnail of the picture you chose will appear to the left of the blocks.
