haha charlie. i got that from AP 
and yes, the higher resolution should win out (unless the resolution of your image is not one rendered by mine) and when IGC inputs the script that will create the smaller resolutions of images that dont have that yet, you will see a bunch of resolutions for the one that i uploaded. in cases where we have a 1920x1200 and a 1600x1200 image both will be kept because the former is widescreen and the latter isnt. also, if the Cyclone program is ever finished, it will be useful to have as many resolutions of a single image as possible in order to fit any persons screen.
as for the tags, i know, since most of those typos are mine. i was gonna ask IGC to input that into the admin module when he had time. its just that (i assume) he is working on the PM system and the forums (editing, BBC code, admin section, etc...) so i havent brought it up yet. it would be easy for me to go in and remove all of the typoed tags since i made most of them 
i was planning on doing this once i had the power but also thought the editing of posts and the PM system was more important atm.
