Cheech had the answer two years ago. He uploaded a pic to a photo hosting site and then used the "Insert Image" button.
There are actually TWO buttons to insert images. The first "Insert Image" [img width=30 height=25]http://nwogeo.org/images/bbcode/img.gif[/img] button inserts the image in it's original size, while the second, called the "Insert Sized Image" [img width=25 height=25]http://nwogeo.org/images/bbcode/img_sized.gif[/img] button allows the image to be resized. Using these buttons should be the preferred method. Other edit buttons such as the Left, Center, and Right alignments can also be applied to the images to help with their presentation.
Images can also be "attached" to the post, however they can not be resized, they consume space and bandwidth on our server, there is a 256k file size cap to the upload, not to mention that they are not displayed in a very presentable manner.
Notice that the "attached" example that Cheech uploaded with him and his gf above, is so large that it causes the forum to need a horizontal scrolling line in the browser.
Here is the same pic [img width=58 height=43]http://nwogeo.org/uploads/forums/dcp02772.jpg[/img] posted at 5% of the orginal size using the "Image Sized" button.
A third and even less desired method would be to add the image to our photo gallery and then link to it with an image button. This method should only be used when the image is of sufficient interest to actually warrant being part of the gallery.
There are plenty of image and video hosting sites out there. The best known of course are PhotoBucket
As far as not being able to upload an image as an attachment, I can only blame that glitch on GoodDogitis.
