Here I've resized to almost 44% and converted to jpg.
I think board limits are 6/700px(?) wide x 250kb's. Your file went to 599x41kb's.
Ta'boot, this boards posting FAQ is WAAAAY outta date!
If you're gonna link, thumbnails keep users with smaller resolutions from having a horizontal scrollbar.Can I post Images?
Images can indeed be shown in your posts. However, there is no facility at present for uploading images directly to this board.
If you want permanence, resize and attach -- It's the *responsible* approach.
